To verify a given pair (p, q) is a solution of the equationax + by + c = 0, We have toput
p in place of x and q in place of y in the given equation .

If LHS became equal to RHS then we conform that (p, q) is a solution of the equationax
+ by + c = 0.

Example:
Check whether (0,2) is a solution of the equation x +2y = 4.
Solution: (0,2) = (x , y)
 x = 0 and y = 2
LHS = x + 2y = 0 + 2x2 = 4 = RHS.
Therefore, (0, 2) is a solution of x + 2y = 4.
Example:
Check whether (0, – 2) is a solution of the equation x +2y = 4.
Solution: (0, –2) = (x , y)
 x = 0 and y = –2
LHS = x + 2y = 0 + 2x(–2) = –4 ≠ RHS.
Therefore, (0, –2) is not a solution of x + 2y = 4.
