Question 699142: When I was born, my father was 41 years old. Eight years ago he was 3 times as old as I will be in 5 years. How old am I? Answer by MathLover1(20849) (Show Source):
You can put this solution on YOUR website! Let be your current age (that is what you are trying to solve for).
The father's age is equal to (father was when you were born).
In years, you will be years old.
years ago, your father was years old, or years old. At that time, the father was three times as old as you will be in years, or .
Now we have an equation that we can solve for with
(the father's age years ago) which is equal to (your age years from now)
so, .....you are years old now
Check this with the original problem to see if the answer makes sense:
you are now
in years you will be years ago you were year old
your father is years old now, so years ago he was
since , means our answer is correct
