The product of the forces and the distances from the fulcrum must be the same on both sides.

X 3 feet from the fulcrum and Y 5 feet; on the other side, 375 pounds at 2 feet:

X 5 feet from the fulcrum and Y 3 feet; on the other side, 385 pounds at 2 feet:

Subtract one equation from the other:

Substitute in one of the original equations:

ANSWERS: 90 pounds for Y and 100 pounds for X.
