how can i solve by elimination
2x+2y=-4
3x=3y+12
how can i get the pair up so i can eliminate y or x

Ok to eliminate you want one side of each of the equations to be the same. So if you isolate the x in the top equation, and multiply everything three, you get 6x=-12 - 6y
Then multiply the bottom equation you multiply by 2 and it becomes 6x=6y+12
Subtract the top equation from the bottom equation. You get 6x - 6x = (6y+12)-(-12-6y)
The 6x - 6x becomes zero, so 0 = 6y + 12 + 12 + 6y and now you can solve for y.

Do the same method, but isolate the "y" instead of the x, and the y's will cancel so you can solve for x.

Multiply (2x +2y=-4) by 3, and (3x =3y+12) by 2. Then subtract the two equations.x will be eliminated
