Devaughn is 8 years older than Sydney. The sum of their ages is 64. What is Sydney's age?

Sydney's age is 28

Step-by-step explanation:

Let Devaughn be D

And Sydney be S

D=S+8 equation 1

D+S=64 equation 2

Substitute equation 1 to equation 2

S+8+S=64

2S+8=64

2S=64-8

2S=56

S=56/2

S=28

Hope it helps
