Question

is (0, -2) a solution of 2x - 5y = 10?yes or no

Answer 1

If it is a solution it would satisfy the equation 2x - 5y = 10

(0, -2).  x = 0,  y = -2

Left Hand side, LHS =2x - 5y

2*0 - 5*-2

0 + 10

10

This is equal to the Right Hand Side (RHS) of the equation.

LHS = RHS.

Yes (0, -2) is a solution to 2x - 5y = 10.
