**Solve the following system of equations graphically:**

**1.** **x + y = 3**

** 2x + 5y = 12**

**Solution: **

**Given,**

**x + y = 3â€¦â€¦. (i)**

**2x + 5y = 12â€¦â€¦. (ii)**

**For equation (i),**

When y = 0, we have x =3

When x= 0, we have y =3

Thus we have the following table giving points on the line x + y = 3

x | 0 | 3 |

y | 3 | 0 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (12 â€“ 2x)/5

So, when x = 1

y = (12 â€“ 2(1))/5 = 2

And, when x = 6

â‡’ y = (12 â€“ 2(6))/5 = 0

Thus we have the following table giving points on the line 2x + 5y = 12

x | 1 | 6 |

y | 2 | 0 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (1, 2)

Hence, x= 1 and y = 2

**2.** **x – 2y = 5**

** Â 2x + 3y = 10**

**Solution: **

**Given,**

**x – 2y = 5â€¦â€¦. (i)**

**2x + 3y = 10â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (x – 5)/2

When y = 0, we have x = 5

When x = 1, we have y = -2

Thus we have the following table giving points on the line **x – 2y = 5**

x | 5 | Â 1 |

y | 0 | -2 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (10 â€“ 2x)/3

So, when x = 5

y = (10 â€“ 2(5))/3 = 0

And, when x = 2

â‡’ y = (10 â€“ 2(2))/3 =2

Thus, we have the following table giving points on the line **2x + 3y = 10**

x | 5 | 2 |

y | 0 | 2 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (5, 0)

Hence, x= 5 and y = 0

**3. 3x+ y + 1 = 0Â **

** 2x – 3y + 8 = 0**

**Solution: **

**Given,**

**3x+ y + 1 = 0Â â€¦â€¦. (i)**

**2x – 3y + 8 = 0â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = -(1 + 3x)

When x = 0, we have y = -1

When x = -1, we have y = 2

Thus, we have the following table giving points on the line **3x+ y + 1 = 0Â **

x | -1 | 0 |

y | 2 | -1 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (2x + 8)/ 3

So, when x = -4

y = (2(-4) + 8)/3 = 0

And, when x = -1

â‡’ y = (2(-1) + 8)/3 = 2

Thus we have the following table giving points on the line **2x – 3y + 8 = 0**

x | -4 | -1 |

y | 0 | 2 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (-1, 2)

Hence, x= -4 and y = 0

**4. 2x + y – 3 = 0**

** Â 2x – 3y – 7 = 0**

**Solution: **

**Given,**

**2x + y – 3 = 0â€¦â€¦. (i)**

**2x – 3y – 7 = 0â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (3 – 2x)

When x = 0, we have y = (3 â€“ 2(0)) = 3

When x = 1, we have y = (3 â€“ 2(1)) = 1

Thus we have the following table giving points on the line **2x + y – 3 = 0**

x | 0 | 1 |

y | 3 | 1 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (2x – 7)/ 3

So, when x = 2

y = (2(2) – 7)/3 = -1

And, when x = 5

â‡’ y = (2(5) – 7)/3 = 1

Thus we have the following table giving points on the line **2x – 3y – 7 = 0**

x | 2 | 5 |

y | -1 | 1 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (2, -1)

Hence, x= 2 and y = -1

**5.** **x + y = 6**

** x – y = 2**

**Solution: **

**Given,**

**x + y = 6â€¦â€¦. (i)**

**x – y = 2â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (6 – x)

When x = 2, we have y = (6 â€“ 2)) = 4

When x = 3, we have y = (6 â€“ 3) = 3

Thus we have the following table giving points on the line **x + y = 6**

x | 2 | 3 |

y | 4 | 3 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (x – 2)

So, when x = 2

y = (0 – 2) = -2

And, when x = 5

â‡’ y = (2 – 2) = 0

Thus we have the following table giving points on the line **x – y = 2**

x | 0 | 2 |

y | -2 | 0 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (4, 2)

Hence, x= 4 and y = 2

**6. x – 2y = 6**

** 3x – 6y = 0**

**Solution: **

**Given,**

x – 2y = 6**â€¦â€¦. (i)**

3x – 6y = 0**â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (x – 6)/2

When x = 2, we have y = (2 â€“ 6)/2 = -2

When x = 0, we have y = (0 â€“ 6)/2 = -3

Thus we have the following table giving points on the line x – 2y = 6

x | 2 | 0 |

y | -2 | -3 |

**For equation (ii),**

**We solve for y: **

â‡’ y = x/ 2

So, when x = 0

y = 0/2 = 0

And, when x = 2

â‡’ y = 2/2 = 1

Thus we have the following table giving points on the line 3x – 6y = 0

x | 0 | 2 |

y | 0 | 1 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines are parallel to each other. So, the two lines do not intersect.

Hence, the given system has no solutions.

**7. x + y = 4**

** 2x – 3y = 3**

**Solution: **

**Given,**

**x + y = 4â€¦â€¦. (i)**

**2x – 3y = 3â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (4 – x)

When x = 4, we have y = (4 â€“ 4) = 0

When x = 2, we have y = (4 â€“ 2) = 2

Thus we have the following table giving points on the line **x + y = 4**

x | 4 | 2 |

y | 0 | 2 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (2x – 3)/3

So, when x = 3

y = (2(3) – 3)/3 = 1

And, when x = 0

â‡’ y = (2(0) – 3)/3 = -1

Thus we have the following table giving points on the line **2x – 3y = 3**

x | 3 | 0 |

y | 1 | -1 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (3, 1)

Hence, x= 3 and y = 1

**8. 2x + 3y = 4**

**Solution: **

**Given,**

**2x + 3y = 4â€¦â€¦. (i)**

**x â€“ y + 3 = 0â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (4 – 2x) /3

When x = -1, we have y = (4 – 2(-1))/3 = 2

When x = 2, we have y = (4 – 2(2))/3 = 0

Thus we have the following table giving points on the line **2x + 3y = 4**

x | -1 | 2 |

y | 2 | 0 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (x + 3)

So, when x = 0

y = ( 0 + 3) = 3

And, when x = 1

â‡’ y = ( 1 + 3) = 4

Thus we have the following table giving points on the line **x â€“ y + 3 = 0**

x | 0 | 1 |

y | 3 | 4 |

Graph of the equations (i) and (ii) is as below:

Clearly the two lines intersect at a single point P (-1, 2)

**3x – 2y + 12 = 0â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (2x + 13) /3

When x = -5, we have y = (2(-5) + 13))/3 = 1

When x = -2, we have y = (2(-2) + 13))/3 = 3

Thus we have the following table giving points on the line **2x – 3y + 13 = 0**

x | -5 | -2 |

y | 1 | 3 |

**For equation (ii),**

**4x – 2y = 5â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (x – 2)/2

When x = 2, we have y = (2 – 2)/2 = 0

When x = 0, we have y = (0 – 2)/2 = -1

Thus we have the following table giving points on the line **x – 2y = 2**

x | 2 | 0 |

y | 0 | -1 |

**For equation (ii),**

**We solve for x: **

â‡’ x = (5 + 2y)/4

So, when y = 0

x = (5 + 2(0))/4 = 5/4

And, when y = 1.5

â‡’ x = (5 + 2(1))/4 = 7/4

Thus we have the following table giving points on the line **4x – 2y = 5**

x | 5/4 | 7/4 |

y | 0 | 1 |

Graph of the equations (i) and (ii) is as below:

It is clearly seen that the two lines intersect at (1,0)

Hence, the system of equations is consistent.

**21. Determine by drawing graphs, whether the following system of linear equation has a unique solution or not:**

**(i) 2x – 3y = 6 and x + y = 1**

**Solution: **

**Given,**

**2x – 3y = 6 â€¦â€¦. (i)**

**x + y = 1â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (2x – 6)/3

When x = 3, we have y = (2(3) – 6)/3= 0

When x = 0, we have y = (2(0) – 6)/3= -2

Thus we have the following table giving points on the line **2x – 3y = 6**

x | 3 | 0 |

y | 0 | -2 |

**For equation (ii),**

**We solve for y: **

â‡’ y = (1 – x)

So, when x = 0

y = (1 – 0) = 1

And, when x = 1

â‡’ y = (1 – 1) = 0

Thus we have the following table giving points on the line **x + y = 1**

x | 0 | 1 |

y | 1 | 0 |

Graph of the equations (i) and (ii) is as below:

Itâ€™s seen clearly that the two lines intersect at one.

Thus, we can conclude that the system of equations has a unique solution.

**(ii) 2y = 4x – 6 and 2x = y + 3**

**Solution: **

**Given,**

**2y = 4x – 6â€¦â€¦. (i)**

**2x = y + 3â€¦â€¦. (ii)**

**For equation (i), **

â‡’ y = (4x – 6)/2

When x = 1, we have y = (4(1) – 6)/2 = -1

When x = 4, we have y = (4(4) – 6)/2= 5

Thus we have the following table giving points on the line **2y = 4x – 6**

x | 1 | 4 |

y | -1 | 5 |

**For equation (ii),**

**We solve for y: **

â‡’ y = 2x – 3

So, when x = 2

y = 2(2) â€“ 3 = 1

And, when x = 3

â‡’ y = 2(3) â€“ 3 = 3

Thus we have the following table giving points on the line **2x = y + 3**

x | 2 | 3 |

y | 1 | 3 |

Graph of the equations (i) and (ii) is as below:

We see that the two lines are coincident. And, hence it has infinitely many solutions.

Therefore, the system of equations does not have a unique solution.
