Q. 8 A

# Let us solve the following equations graphically.

4x – y = 3; 2x + 3y = 5

Answer :

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:
