You can put this solution on YOUR website! If one person is 10 years old and another person is 42 years old, what is the equation to figure out how old each person is when the 42 year old is exactly 3 times as old as the 10 year old?
--------------------
The difference is 32 yrs.
If the older is 3x, the difference is 2x.
-----------------
Why ask "what is the equation?"
Ask, "How do you find the answer?"
-----
If there is always an equation, how many can a person memorize?
===================
Also, "exactly 3 times as old" won't work. You have to round down to the # of years of age, not the weeks, days, or seconds.
