how did you simplify?

This probably seemed like a trick question, since you can't reduce the fraction farther or combine the two terms. What you'll need to do is reorder the terms. In general, you start by writing the term with the largest exponent and then work towards the constant term. Also, the coefficient (7) would go in front of the variable (v) instead of after it.

7v + 5/8
