Question

In parallelogram DEFG, DH = x + 4, HF = 3x, GH = 3x + 4, HE = 5y - 5. Find the values of x and y.

Answer 1

parallel sides are congruent, and the diagonals bisect each other. I have no idea where H is. But setting equal sides' lengths equal, you will have two equations to solve for x and y.
