I don't know of a way to solve it, but the answer is x= -4 and y =4.  It works in both equations.

Normally I would solve this by multiplying the first equation by -2, so the 2x would be come -4x and I could add the 2 equations together, the x's would cancel each other out,  and I could solve for y, and then solve for x.  However, in multiplying the first equation by -2, I would end up cancelling both he x's and the y's.  So I just tried a couple numbers until I found the right ones.
