Question

Justin weighs 15 pounds less than Greg weighs. Half of Greg's weight is 75 pounds less than Justin's weight. How much does each of them weigh?

Answer 1

justin = 135 & greg = 150

Explanation:

equations:

(justin is 15lbs under greg) j-15=g

(find gregs full weight by doubling bc the problem gave you half) 75*2=150

(plug in gregs wieght to find justins weight) j-15=150 -> j=135
