x = -2
y = -4
Step-by-step explanation:
After adding both equations, you would then have
0 + 11y = -44
11y = -44
y = -44/11
y = - 4
Now, you substitute for y in either of the first equations. I'm using the second one.
-3x + 2(-4) = -2
-3x - 8 = -2
-3x = -2 + 8
-3x = 6
x = -6/3
x = -2
Therefore, x = -2 and y = -4
You can test for it by substituting both in the equation
-3(-2) + 2(-4) =
6 - 8 = -2
