Question

Draw the graphs of equations 2y + x = 7 and 2x + y = 8. Write the co-ordinates of the point of their intersection.

Answer 1

2y + x = 7

The table with the values of x and y satisfying the given equation is shown below:

x	3	1
y	2	3

2x + y = 8

The table with the values of x and y satisfying the given equation is shown below:

x	3	2
y	2	4

The graph of the lines is given below:-



Coordinates of the point of intersection, i.e. P are (3,2).
