Question

Joe is 5 years younger than his brother. 3 years ago, the sum of their age was 25. Find their ages.

Answer 1

Answer:

Step-by-step explanation:

Let the age of Joe's brother be x

Age of Joe = x-5

According to question,

Age of Joe 3 years ago = x-5-3

Age of Joe's brother 3 years ago = x-5

(x-5) + (x-5-3) = 25

x+x + (-5-5-3) = 25

2x = 25 +5+5+3

2x = 38

x = 38/2

x = 19

Age of Joe's brother = 19

Age of Joe = 19 - 5 = 14
