Question

Bill weighs 120 pounds and is gaining 12 pounds each month. Phil weighs 200 pounds and is losing 4 pounds each month. How many months will it take for Bill to weigh the same as Phil?​

Answer 1

Explanation:

B=120+12m and P=200-4m

120+12m=200-4m add 4m to each side

16m+120=200, subtract 120 from each side

16m=80, divide each side by 16

m=5

So in five months they will weigh the same.
