    3x + 2y = 10 ----> equation(1) 2x - 3y = 12 ----> equation(2) multiply equation(1) by -2 and equation (2) by 3 -6x - 4y = -20 6x - 9y = 36 -------------------- -13y = 16 y = -16/13 Substitute y = -16/13 into equation(1) or equation(2) to solve for x, 3x + 2y = 10 3x + 2(-16/13) = 10 3x - 32/13 = 10 39x - 32 = 130 39x = 162 x= 162/39 = 54/13
