$\text{$\frac{-3}{4}$×$\frac{-5}{12}$÷$\frac{-5}{4}$=2x-$\frac{5}{8}$}$
$\text{⇒ 2x-$\frac{5}{8}$=$\frac{-3}{4}$×$\frac{-5}{12}$×$\frac{4}{5}$}$
$\text{⇒ 2x-$\frac{5}{8}$=$\frac{-3}{4}$×$\frac{-1}{3}$}$
$\text{⇒ 2x-$\frac{5}{8}$=$\frac{1}{4}$}$
$\text{⇒ 2x=$\frac{1}{4}$+$\frac{5}{8}$}$
$\text{⇒ 2x=$\frac{7}{8}$}$
$\text{⇒ x=$\frac{7}{16}$}$
