When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:
![\frac{3^2 + 3}{3 - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%5E2%20%2B%203%7D%7B3%20-%201%7D%20%20)
After this, we merely need to simplify the answer.
![\frac{9 + 3}{3 - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%20%2B%203%7D%7B3%20-%201%7D%20%20)
![\frac{12}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B2%7D%20%20)
Simplifying 12/2 gives us the answer 6.
