Answer:

x = 6, y= -6

Step-by-step explanation:

-4x - 2y=-12

4x + 8y = -24

Add the two equations together to eliminate x

-4x - 2y=-12

4x + 8y = -24

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

6y = -36

Divide each side by 6

6y/6 = -36/6

y = -6

Now we can find x

4x+8y = -24

4x +8(-6) = -24

4x -48= -24

Add 48 to each side

4x -48+48 = -24+48

4x = 24

Divide each side by 4

4x/4 = 24/4

x =6
