Question 1012044
A mother is nine times as old as her son. In three years, she will be five times as old as her son. Find the present age of each. 
------
Equations:
m = 9s
m+3 = 5(s+3)
-----
Substiute for "m" and solve for "s"::
9s + 3 = 5s + 15
4s = 12
Son's age = 3 yrs
----------
Solve for "m"::
m = 9s
Mum's age = 9*3 = 27 yrs
