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
