Question

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

Answer 1

Sydney is 26 years old. Devaughn's age would be 2 times 26, making him 52. And 52+26=78. If you'd like further explanation as to how I came to this answer, I'd be glad to help. :)

Answer 2

x is Sydney's age
2x is Devaughn's age

x +2x = 78
3x = 78
x = 78/3
x = 26
answer:

Sydney is 26 years old
