Re: [math-fun] Problem for John's son

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 ? Le 2016-06-18 à 04:53, Zak Seidov via math-fun a écrit :
