Problema Solution
Bob weighs 10 pounds more than Sam. Jim weighs 12 more pounds than Bob. Together they weigh 422 lbs.How much does each weigh?
Answer provided by our tutors
let 'x' represent Sam's weight, then 'x+10' represents Bob's weight and 'x+10+12' represents Jim's weight
422 = x + x+10 + x+10+12
solving for 'x' we have x=130
130+10=140
140+12=152
Sam weights 130, Bob weighs 140 and Jim weights 152
