A) write an equation that relates cindys age to her dads age .
B)determine if 42 is a solution to the equation. Show
 your work.
C) explain the meaning of your answer in part B.

Answer 1

so dad=28
cindy=2
so 28-2=diffirance in age=26

A. dad-26=cindy
cindy=dad-26
dad=cindy+26
so since cindy=18
dad=18+26=44

B. if dad =42=cindy+26 so
42=x+26
subtract 26 from both sides
16=x
cindy =16 if dad =42

C. so the number of years apart they will be will always be 26 (until one of them dies)
