Question 255484
Let's use the addition method here.  If we multiply the first equation by 2, we will be able to eliminate y.  So we have:

8x + 4y = -4
3x - 4y = -18

If we add these two together we are left with:

11x = -22

So x = -2.  If we substitute this back into the original 1st equation, we can find y:

4(-2)+ 2y = -2
-8 + 2y = -2
2y = 6
y=3

So the solution is (-2,3).
