    4x-4y=-40 -4x+7y=55 ----------- 3y=10 y=10/3 Put this value in one of the equation to gt x if this is linear equation in two variables.

    not quite if you add the 2 equations 4x - 4y = -40 -4x + 7y = 55 -------------- 3y = 15 that might make for an easier answer

    just solve for y then substitute into either equation to find x
