Answer

-$\frac{19}{15}$

Work Step by Step

In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 2/3 by 5/5 and 3/5 by 3/3 (this is legal because 5/5 and 3/3 equal one) to obtain: -$\frac{10}{15}$+(-$\frac{9}{15}$)=-$\frac{19}{15}$
