    I'm not sure if you want the answer or how to do i'll just give you both.

    multiply the bottom by - 4. then it should look like:

    8x-6y=-6

    -8x+16y=56

    then cancel out the x's and add/subtract the others, giving you: - 2y=50. then divide 50 by - 2 giving you: y=-25. then find x. plug in y to one of the equations. i usually do the one that hasn't been messed with. 8x-6 (25) = -6. then solve it like a normal two-step equation.

    so the answer is: (18,-25)
