Devaughn is
14
years younger than sydney. the sum of their ages is
58
. what is sydney's age?

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

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
