A man is 5 times as old as his son. In 5 years he will be nly 3 times as old as his son. Find the present age of each
--------------
Equations:
F = 5S
(F+5) = 3(S+5)
---------------------
Substitute for "F" and solve for "S":
(5S + 5) = 3S + 15
2S = 10
S = 5 yrs old (Son's age now)
----
Since F = 5S, F = 25 yrs old (Father's age now)
