Question 646132
<pre>
You will always be 34 years older than your daughter.  When she is X,
you will be 34+X.  You want to know when your age, 34+X, will be equal
to 3 times her age, X, which will be 3X

So the equation is

        Your age = 3(her age)
          34 + X = 3(X)
          34 + X = 3X
             - X   -X
         -------------
          34     = 2X
              17 = X

When she is 17, you will be 34 years older than that or 17+34 = 51
and 3·17 = 51.
