Question

Devaughn is

14
years younger than Sydney. The sum of their ages is
58
. What is Sydney's age?

Answer 1

d= devaughn
s=sydney


s-d=14
s+d=58


*now you cancel out the d values because one is negative, and one is positive*

s=14
s=58

*combine the two equations*
2s=72
/2 /2
s=36
sidney is 36 years old, now plug 32 into one of the original equations, in order to find devaughns age.

d+36=58
-36 -36
d=22 devaughn is 22 years old

Answer 2

if you subtract 58 by 14 you will get 44 so thats the answer
