Question

Roberto is 14 years older than Tre. Five years ago, the sum of their ages was 28. How old are they now?

Answer 1

Answer: Roberto is 26 years old and Tre is 12 years old.

Explanation:

Let T=age of Tre

14+T=age of Roberto

14+T+T=28

14+2T=28

2T=14

T=7(Tre’s age 5 years ago)

14+T=14+7=21(Roberto’s age 5 years ago))

7+5=12 years old

21+5=26 years old

To check:

26-12=14

So Roberto is 14 years older.
