Question 130930
George weighs 60 lbs. more than 1/2 his younger brother Galen's weight. If their weights balance when George is 4 ft. from the fulcrum on a 10 ft. long teeterboard, what are their weights?
-------------------
Let his brother's weight be "x" lbs. ; George = (x/2) + 60
EQUATION:
4[(x/2) + 60] = 10x
2x + 240 = 10x 
8x = 240
x = 30 lbs : brother's weight
-----------------------------
(x/2) + 60  = 75 lbs. :George's weight
