Question

Gabrielle is
7

years older than Mikhail. The sum of their ages is
91

. What is Mikhail's age?

Answer 1

42

Explanation:

Since Gabrielle is 7 years older than Mikhail, we subtract 7 from 91. Then we divide it by 2. So 84/2=42. Since Gabrielle is 7 years older we add 7 to 42. She is 49 and Mikhail is 42 years old. To double check our answer we should add both of the ages we got to make sure they add up to 91, so 42+49 is 91.
