How do you solve 2/7k - 3/8 = -19/8

1 answer:

8 0

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
