Question

Gabriele is 15 years older than Mikhail. The sum of their ages is 91. What is Mikhail's age?

Answer 1

It is given that the sum of their ages are 91.

It is also given that Gabriele is 15 years older than Mikhail age.

Let Mikhail age be x and Gabriele age be y.

The equation formed is

`y=x+15`
`y-x=15`

Another equation is

`x+y=91`

Solve the two equations to determine the value of x and y

`2y=106`
`y=53`

Substitute the value of y in the equation to find x

`x+53=91`
`x=38`

Hence the age of Mikhail is 38 year and Gabriele age is 53 year.
