Answer
x = -2
Work Step by Step
-$\frac{3}{8}$x = $\frac{3}{4}$
To get x by itself, and cancel out -$\frac{3}{8}$, multiply both sides by the reciprocal of -$\frac{3}{8}$:
(-$\frac{8}{3}$)(-$\frac{3}{8}$)x = ($\frac{3}{4}$)(-$\frac{8}{3}$)
($\frac{3}{4}$)(-$\frac{8}{3}$) = - $\frac{24}{12}$
x = -24 $\div$ 12 = -2
x = -2
