Gabrielle's age is two times mikhail's age. the sum of their ages is 45. what is mikhail's age?

Mikhail's age = 15 years and Gabrielle's ageis 30 years

Step-by-step explanation:

let Mikhail's age be x years

then Gabrielle's age is 2x years

x+2x=45

3x=45

x= 45/3=15 years

your answer would be 10x - 1
