Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1 equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3 subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10 -1/4 x = 28 x=-112 plug in x=-112 in any of the equation, you will get y=-264 so the answer is A
