Question 255484: 4x+2y=-2
3x-4y=-18
Answer by EMStelley(208)   (Show Source):
You can put this solution on YOUR website! 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).
