Question

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

Answer 1

Answer:

33

Step-by-step 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.
