Question

Devaughn's age is three times Sydney's age. The sum of their ages is 24 . What is Sydney's age?

Answer 1

Let, the age of Sydney = x
Age of Devaughn = 3x

It is given that, x + 3x = 24
4x = 24
x = 24/4
x = 6

In short, Sydney is 6 Years old

Hope this helps!

Answer 2

Sydney's age = x
Devaughn's age= 3x

So you get the equation:
x+3x=24
4x=24 (combine like terms)
x=6 (divide both sides by 4)
