weighs 67 lb and sits on the opposite side of the seesaw at a distance of 48 inches from the

fulcrum. Mikey weighs 30 lb and wants to play but doesn’t know where to sit in order to make

the seesaw exactly balance. On whose side and how far away from the fulcrum should he sit?

**MathMate**, Sunday, December 5, 2010 at 10:01pmTake moments about the fulcrum, and assume Mikey sits on Joey's side. If the distance turns out negative, go to the other side.

Take moments about the fulcrum, clockwise=positive

67*48 - (77*30 + 30*x ) = 0

Solve for x
