let's firstly convert the mixed fractions to improper fractions.


\stackrel{mixed}{3(2)/(7)}\implies \cfrac{3\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{23}{7}} \\\\[-0.35em] ~\dotfill\\\\ -\cfrac{23}{7}-\left(-\cfrac{5}{7} \right) \implies -\cfrac{23}{7}+\cfrac{5}{7}\implies \cfrac{-23+5}{7}\implies \cfrac{-18}{7}\implies {\Large \begin{array}{llll} -2(4)/(7) \end{array}}
