Question

Jon weighs 148 lb and hopes to gain 2 lbs a week.Matt weighs 193lb and hopes to lose 1 lb a week.How many weeks until the weight the same?

Answer 1

set up the equation:

Let x be the number of weeks before they weigh the same.

148+2x=193-x

solve:

148+2x=193-x
3x=45
x=15

therefore: it will take 15 weeks until they weigh the same.
