Answer: it will take 14 months for their weights to be the same.
Step-by-step explanation:
Let x represent the number of months it will take for their weights to be the same.
Katy weighs 105 pounds and is gaining 2 pounds a month. This means that the total weight of Katy after x months is
2x + 105
James weighs 175 pounds and is losing 3 pounds a
month. This means that the total weight of James after x months is
175 - 3x
For their weights to be the same, it means that
2x + 105 = 175 - 3x
3x + 2x = 175 - 105
5x = 70
x = 70/5
x = 14
