Step-by-step explanation:

You have two equations and two "unknowns" x and y.

This is an easy one. Add the two equations together, which will eliminate the y terms so you can solve for x:

2x+2y = -2

3x-2y = 12

---------------

5x  = 10,   so x = 2.

Now plug the 2 back into one of the equations and solve it for y.

2(2)+2y = -2

4+2y = -2

2y = -6

y = -3
