x + y = -4

x - y = 2

x + y = -4

x - y = 2

In the second equation,

x= y+2 Putting that in the first..

(y+2) + y= -4

subtract two from each side, then divide each side by two to get y. Then, put that value of y into EITHER of the equations and solve for x. I will be happy to critique your thinking or work.
