$\frac{-2}{3}$ – $\frac{1}{3}$(2x – 5) = $\frac{3}{2}$
$\frac{1}{3}$(2x – 5) = $\frac{-2}{3}$ – $\frac{3}{2}$
$\frac{1}{3}$(2x – 5) = $\frac{-13}{6}$
(2x – 5) = $\frac{-13}{6}$ : $\frac{1}{3}$
2x – 5 = $\frac{-13}{2}$
2x = $\frac{-13}{2}$ + 5
2x = $\frac{-3}{2}$
x = $\frac{-3}{2}$ : 2
x = $\frac{-3}{4}$
