a father'age is twice his daughter's age but 16 years ago the father's age was 4 times his daughter's age. Calculate their ages.
-----------------
Equations:
f = 2d
f-16 = 4(d-16)
-----
Substitute for "f" andsolve for "d":
2d-16 = 4d-64
2d = 48
d = 24 (daughter's age now)
---
Solve for "f":
f = 2d
f = 2*24 = 48 (father's age now)
