    The diagonals of a parallelogram bisect each other. That means y = 3x and y + 12 = 6x You need to solve that system of equations.

    Since y = 3x, plug that in for y of the other equation: 3x + 12 = 6x

    That will give you x, then plug the value of x into y = 3x, and you'll get y.

    3x + 12 = 6x 12 = 3x x = 4 y = 3x y = 3(4) y = 12
