How old is John when John is 13 years less than 3 times as old as his son?
John is 13 years less than 3 times as old as his son. Six years ago, he was 14 years more than twice as old as his son was then. How old is John?
J = 3*s - 13 (John is 13 years less than 3 times his son's age)
J - 6 = 2(S - 6) + 14 (6 years ago he was 14 more than twice his son's age 6 years ago)
Substitute the first equation for J into the second equation.
John's currently 50, and his son is 21.
