Question

Gabrielle’s age is two times Mikhail’s age. The sum of their ages is 36. What is Mikhail’s age?

Answer 1

Mikhail’s age is 18.

2x=36
divide both sides by two and the answer you get is 18.

To check your answer you can just do 18+18 and that equals 36, which is the sum of their ages, as stated in the question.
