Answer:

Kim is 13
Jack is 8

Step-by-step explanation:

Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...

k + (k -5) = 21

2k = 26 . . . . . . . add 5, collect terms

k = 13 . . . . . . . . . divide by 2; Kim's age

k -5 = 8 . . . . . . . Jack's age

Kim is 13; Jack is 8.
