Question 1188023
dawn is m year old now.


eugene is 6 times as old as dawn.
that makes eugene 6m years old.


aaron is 11 years older than eugene.
that makes aaron 6m + 11 years old.


how old was aaron 5 years ago?
5 years ago, aaron was 6m + 11 - 5 = 6m + 6 years old.
that's your solution.


for example:
assume dawn is 2 years old now.
that makes eugene 6 * 2 = 12 years old now.
that makes aaron 12 + 11 = 23 years old now.
5 years ago, aaron was 23 - 5 = 18 years old.
6 * 2 + 6 = 12 + 6 = 18, confirming the solution is correct.
