why did u post this in the history section? :o
in 5 years, jacob's age = J+5
in 5 years, his son's age = S+5
but Jacob will be 3 times older than his son, therefore
J=3S+10 --------------(equation 1)
5 years ago, jacob's age = J-5
5 years ago, his son's age = S-5
but Jacob was 7 times older than his son, therefore
J=7S-30 --------------(equation 2)
