let father's age be f and son's age s
if a father is five time as old as his son, we have
f=5s ....eq.1
if the sum of their age last year was 58+years, we have
%28f-1%29%2B%28s-1%29=58
f%2Bs-2=58
f%2Bs=58%2B2 ...substitute f from eq.1
5s%2Bs=60
6s=60
s=10
go to
f=5s ....eq.1,..substitute s
f=5%2A10
f=50

the present age of the son is 10
