A father is three times as old as his son 5 years ago fathers age was four times his son age then find their present ages
------
Equations:
f = 3s
f-5 = 4(s-5)
------
Substitute for "f" and solve for "s"::
3s-5 = 4s-20
----
Son's age = 15 yrs
---------------------------
Solve for "f"::
f = 3s
Father's age = 3*15 = 45 yrs
