$6\frac{23}{35}$

We start by adding the whole numbers: 2+3=5. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 6/7 by 5/5 and 4/5 by 7/7 to obtain: $\frac{28}{35}$+($\frac{30}{35}$)=$\frac{58}{35}=1\frac{23}{35}$. We add 5 to this to get a total of $6\frac{23}{35}$.
