Question 170797
Paul is 12 and his father is 33. How many years ago was the father four times as old as the son?
-----------------------------------
NOW DATA:
Paul = 12
Father = 33
-----------------------
x years ago DATA:
Paul = 12-x
Father = 33-x
-----------------------
EQUATION:
father = 4*paul
33-x = 4(12-x)
33-x = 48 - 4x
3x = 15
x = 5 (# of years ago)
