Question

Devaughn is 14 years older than Sydney. The sum of their ages is 110. What is Sydney's age?

Answer 1

The answer would be 48

Sydney is 48

Devaughn is 62

48 + 62 = 110

Okays so you start by doing the equation 110 - 14 = 96

then dividing 96 by 2 (96 ÷ 2) which is 48

add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^

Answer 2

d = s-14
d+s = 76

• substitution;
(s-14)+s = 76
2s-14= 76
2s = 90
s = 45 years old for Sydney
d = s-14 = 31 years old for Devaughn
hope this helps
