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
