Question

Gabrielle is 15 years older than Mikhail. The sum of their ages is 81. What is Mikhail's age?

Answer 1

33

Explanation:

let g be Gabrielle age

m be mikhail age.

So according to this problem,

`g + m = 81`

`m + 15 = g`

Subsitue m+15 for g.

`(m + 15) + m = 81`

`2m + 15 = 81`

`2m = 66`

`m = 33`

So mikhail age is 33.
