$x = - \frac{36}{25}$ $x=-36/25$

$- \frac{5}{8} x = \frac{9}{10}$ $-5/8x=9/10$

Simplify $- \frac{5}{8} x$ $-5/8x$ to $\frac{- 5 x}{8}$ $(-5x)/(8)$ .

$\frac{- 5 x}{8} = \frac{9}{10}$ $(-5x)/8=9/10$

Cross multiply.

$- 5 x \cdot 10 = 8 \cdot 9$ $-5x*10=8*9$

$- 50 x = 72$ $-50x=72$

Divide both sides by $- 50$ $-50$ .

$x = - \frac{72}{50}$ $x=-72/50$

Simplify.

$x = - \frac{36}{25}$ $x=-36/25$
