Question

Gabrielle is 13 years older than Mikhail. the sum of their ages is 113. what is mikhails age?​

Answer 1

50 years old

Explanation:

Let's say that Mikhail's age is x.

If so, Gabrielle's age would be 13 years older, therefore x + 13

We know that the sum of their ages is 113, so we can form this equation:

x + x + 13 = 113

Solving this equation, we get:

x + x = 100

2x = 100

x = 50

50 is Mikhail's age, so Gabrielle's age is 63

Answer 2

g=m+13

g+m=113
