Question

Find the value of A so that the point (3,A) lies on the line represented by 2x-3y+5=0 .

Answer 1

i ) It is given that ,

( 3 , a ) lies on the line 2x - 3y + 5 = 0

Substitute x = 3 , y = a in the equation

We get ,

2 × 3 - 3 a + 5 = 0

6 - 3a + 5 = 0

11 - 3a = 0

11 = 3a

11/3 = a. (answer)



If your question is 2x-3y-5=0 then



i ) It is given that ,

( 3 , a ) lies on the line 2x - 3y - 5 = 0

Substitute x = 3 , y = a in the equation

We get ,

2 × 3 - 3a - 5 = 0

6 - 3a - 5 = 0

1 - 3a = 0

1 = 3a

1/3 = a
