Question

Find whether (0, −3) is a solution of linear equation, x – y + 3 =0?

Answer 1

x=o & y=-3
0-3+3=0
0=0

Answer 2

Hi ,

Substitute ( 0 , - 3 ) in given equation

x - y + 3 = 0

0 - ( - 3 ) + 3 = 0

3 + 3 = 0

6 = 0 ( false )

Therefore ,

( 0 , - 3 ) is a not a solution of given

Linear equation.

I hope this helps you.
