Mathematics

Alright, start with simplifying both sides
\frac{2}{7} k+ \frac{-3}{8} = \frac{-19}{8}
Than add \frac{3}{8} to both sides.
\frac{2}{7}k + \frac{-3}{8} + \frac{3}{8} =\frac{-19}{8} + \frac{3}{8}
which is \frac{2}{7} k=-2

After this, multiply each side by \frac{7}{2}
( \frac{7}{2})* \frac{2}{7} k= ( \frac{7}{2})*(-2)
 So, your final answer is K=-7
