Jim is older then Kelsey. The sun of their ages is 88 and the difference of their ages is 30. Write a system of equations to represent this situation. how old is Jim? How old is Kelsey?

System of equations •y+x=88 •y-x=30

Step-by-step explanation: Let x represent Jim and y represent Kelsey.

1. The problem says the sum of their ages is 88 in order to get 88 you would have to add x (Jim) and y (Kelsey) together. By doing this you would get y+x=88

2. The problem says that the difference of their ages is 30. In order to get 30 you would subtract x (Jim) from y (Kelsey) By doing this you would get y-x=30
