Lever Question Algebra 1

Question

An 88-pound boy sits on one end of a 15-foot board, 4 feet from the point of balance. His friend comes along and gets on the other side at a position which enables them to balance. How far from the fulcrum will the friend be if he weighs 64 pounds?

Answer 1

88(4) = 64x

x = 88(4)/64 = 11(4)/8 = 11/2 = 5 1/2 feet

Answer 2

88 * 4 = 64* x

352=64*x

x = 352/64 = 5.5
