## Homework Statement

son and father and granpa have same value for their birthday (except the year ostensibly)

father is nine times the son's age now. calculate the granpa's age now.

clues

- five years ago, grandpa was 32 years older than what the father was at five years ago.

-in five years time, granpa will be 56 years older than what the son would be in five years time.

## Homework Equations

## The Attempt at a Solution

son's age = x

father's age = 9x

granpa = y

five years ago, everybody was younger and limber and more active at these values

x-5

9x-5

y-5 (however granpa was at this age already somewhat older than the father.)

it was said that five years ago granpa was much older than the father at that same time. we must balance the equation between granpa and father

y-5 = 9x-5 +56

y= 9x +56

I got stuck there with nowhere to go about solving the problem.

This was prob the second most difficult problem in our math class...

Clues would be welcome as to what would be prudent tactic to solve this dreadful age riddle .
