Depends on what is meant by "older than his son by 6 times." Simon apparently read it as the father is 6 times his son's age. I would have read it as, the amount that the father is older is 6 times ("by 6 times"), so the father is 7 times his son's age. In that case, the father was 35 and the son 5, then 36 and 6.

the solution is ;
s = son, f= father
now +1 year
s x/6 x/6 + 1
f x x + 1
by solving we get that the father was 24 year old, the son is 4 years old a year later, the father is 25 and the son is 5.
Simon Plouffe ps : I missed something ?
