Q8 of 58 Page 44

Let us solve the following equations graphically.

4x – y = 3; 2x + 3y = 5

4x – y = 3


Putting different values of x, we get different values of ‘y’, hence we get points for plotting as:



2x + 3y = 5


Putting different values of x, we get different values of ‘y’, hence we get points for plotting as:
