We have that in this case the following equalities are met: DH = HF x + 3 = 3y GH = HE 3x - 3 = 5y + 4 We then have the following system of equations: x-3y = -3 3x-5y = 7 Resolving the system graphically we obtain the following values: x = 9 y = 4 Note: see attached image. Answer: The values of x and y are: x = 9, y = 4
