Let x be Hypotenuse’s weight so that Paulie weighs 3x. Let y be the weight of the empty wagon. The puppy on the wagon weighs 40 pounds so: x+y=40(1) Pauli and the puppy on the wagon weighs 64 pounds so: 3x+x+y=64 4x+y=64(2) Solve for yy, the weight of the empty wagon. Using (1), solve for xx in terms of yy to obtain (3): x=40−y(3) Substitute (3) to (2) and solve for yy: 4(40−y)+y=64 160−4y+y=64 160−3y=64 −3y=−96 y=32 So, the empty wagon weighs 32 pounds.
