Question 589336
A mother is three times as old as her son. Six years ago she was five times as old as her son. What is their present age?
------------------
Equations:
m = 3s
(m-5) = 5(s-5)
---
Substitute for "m" and solve for "s":
3s-5 = 5s-25
2s = 20
s = 10 yrs. (Her son's age)
---------------------------
Solve for "m":
m = 3s
m = 30 yrs (Mom's age)
