Answer: x=-2, y=-4

Step-by-step explanation:

Multiply the first equation by 3 to get -6x+6y=-12. Then multiply the second equation by 2 to get 6x+6y=-36. Add both equations, resulting in 12y=-48. Divide both sides by 12 to get y=-4. Then substitute -4 for y in either of the original equations. I'll use the first equation, but it doesn't matter which one you choose. -2x+2(-4)=-4. Multiply the 2 and -4 to get -2x-8=-4. Add over the 8 to get -2x=4. Finally divide by -2 to get x=-2
