Question

tell wether the equation is a solution to the linear equation (0,2);3x-2y=4,-2x-y=-2

Answer 1

To tell whether this solution works, you must plug (0, 2) into both equations. Put a 0 where you see an x and a 2 where you see a y.

3(0) - 2(2) = -4
-2(0) - 2 = -2

Since -4 does not equal 4 in the first equation, (0, 2) is not a correct solution, even though (0, 2) did work for the other equation.
