Jeff is 4 times older than his daughter. Five years ago he was 9 times older than his daughter. Write an algebraic equation to determine the age of his daughter.

Jeff is 32, His Daughter is 8

The relationship between the age of Jeff and his daughter can be summarized by the following systems of equation:

Jeff's age = x

Jeff's Daughter's age = y

x=4y    jeffs age is equal to his daughters times four

x-5=9(y-5) jeffs age minus five is equal to his daughters age minus five as well times 9

Combining these equations will get us x=32, y=8.
