Devaughn's age is two times Sydney's age. The sum of their ages is 87 . What is Sydney's age?

1 answer

Let's denote Devaughn's age as D and Sydney's age as S.

Given that Devaughn's age is two times Sydney's age, we can write:
D = 2S

The sum of their ages is 87, so we can write:
D + S = 87

Substitute the value of D from the first equation into the second equation:
2S + S = 87
3S = 87
S = 87 / 3
S = 29

Therefore, Sydney's age is 29 years old.
