    for elimination, you want to add or subtract your two equations to eliminate one of your variables

    in your case we can just subtract one from the other because that will eliminate the x variable:

    (6-6)x+(3-2)y=((-12)-(-4))

    which is:

    0x+1y=-8

    so now you know that y = -8, and you can use the original equations to find x.
