$$= \frac { 3 } { 8 } x = x - \frac { 15 } { 2 }$$

$x=12$

Subtract $x$ from both sides.

$$\frac{3}{8}x-x=-\frac{15}{2}$$

Combine $\frac{3}{8}x$ and $-x$ to get $-\frac{5}{8}x$.

$$-\frac{5}{8}x=-\frac{15}{2}$$

Multiply both sides by $-\frac{8}{5}$, the reciprocal of $-\frac{5}{8}$.

$$x=-\frac{15}{2}\left(-\frac{8}{5}\right)$$

Multiply $-\frac{15}{2}$ times $-\frac{8}{5}$ by multiplying numerator times numerator and denominator times denominator.

$$x=\frac{-15\left(-8\right)}{2\times 5}$$

Do the multiplications in the fraction $\frac{-15\left(-8\right)}{2\times 5}$.

$$x=\frac{120}{10}$$

Divide $120$ by $10$ to get $12$.

$$x=12$$
