Answer:
x = -1
Step-by-step explanation:
3x + 2y = -7
2x - 2y = 2
First, we need to find a way to cancel out one of the variables. This problem makes it easy because the +2y and -2y will cancel out already. We then add the equations together.
3x + 2y = -7
+ 2x - 2y = 2
-------------------------
5x = -5
Now, we simply divide both sides by 5 to isolate the x.
5x/5 = -5/5
x = -1
This leaves us with x = -1.
Hope this helps!
