Heya! (Rofl)

I need help in how to do this equation. I need to find both x and y.

I tried to multiply the top line with -2, then add both of the lines up, (which would cancel out the -6 and 6: so I'm left with the y's), but I end up with this negative, decimal answer, after working everything out. It doesn't seem right.

So could you guys help me solve it? Thanks! =]

3x + 2y = 22

6x + 5y = 46
