Hey friend,
Here is the answer you were looking for:
\begin{gathered} - \frac{3}{4} + \frac{7}{ - 8} = \frac{7}{ - 8} + ( - \frac{3}{4} ) \\ \\ - \frac{3}{4} + ( - \frac{7}{8} ) = - \frac{7}{8} - \frac{3}{4} \\ \\ - \frac{3}{4} - \frac{7}{8} = - \frac{7}{8} - \frac{3}{4} \\ \\ \frac{ - 3 \times 2 - 7 \times 1}{8} = \frac{ - 7 \times 1 - 3 \times 2}{8} \\ \\ \frac{ - 6 - 7}{8} = \frac{ - 7 - 6}{8} \\ \\ = \frac{ - 13}{8} = \frac{ - 13}{8} \end{gathered}
