$(\frac{8}{35}-\frac{13}{28}i)$

Adding the real parts together and the imaginary parts together, Step 1: $(-\frac{1}{5}+\frac{2}{7}i)+(\frac{3}{7}-\frac{3}{4}i)$ Step 2: $(-\frac{1}{5}+\frac{3}{7})+(\frac{2}{7}i-\frac{3}{4}i)$ Step 3: $(\frac{-7+15}{35})+(\frac{8i-21i}{28})$ Step 4: $(\frac{8}{35}-\frac{13}{28}i)$
