    Part A) to solve for variable y is to make y the subject; 3x + 2y = 16 2y =16-3x y =(16-3x)/2 y = 8 - 1.5x Part B) we now substitue x = -4 into the equation in part A ; y = 8 - 1.5(-4) y = 8 + 6 = 14

    in my book it said that the answer for (A) was -3/2x + 8 and (B) was y=14

    that would be right for my solution. y = -1.5x + 8 = -3/2x + 8
