Answer:

13 years old

Step-by-step explanation:

You would set up your equation like so: 1/2(34)- 9

First, you need to multiply the 1/2 and the 34, which is the same as dividing 34 by 2. For this you get 22. Your equation now looks like 22 - 9.

Second, subtract 9 from 22, getting 13.

It would be 13 years old.
