Question 406304
Jorges father is 4 times as old as Jorge is. In 20 years his father will only be twice as old as Jorge. How old are Jorge and his father now?
----
Equations:
f = 4J
(f+20) = 2(J+20)
------
Substitute for "f" and solve for "J":
(4J+2) = 2J+40
2J = 38
J = 19 yrs (Jorge's age now)
---
Solve for "f":
f = 4J = 4*19 = 76 yrs (father's age now)
