$\dfrac{3}{4}$ + $\dfrac{5}{8}$ : x = $\dfrac{1}{12}$

<=> $\dfrac{5}{8}$ : x = $\dfrac{1}{12}$ – $\dfrac{3}{4}$

<=> $\dfrac{5}{8}$ : x = $-\dfrac{2}{3}$

<=> $x =$ $-\dfrac{5}{8}$ : $(-\dfrac{2}{3})$

<=> x = $-\dfrac{15}{16}$

Vậy x= $-\dfrac{15}{16}$

$\frac{3}{4}$+$\frac{5}{8}$:x=$\frac{1}{12}$

$\frac{5}{8}$:x=$\frac{1}{12}$-$\frac{3}{4}$

$\frac{5}{8}$:x=$\frac{1}{12}$+$\frac{-9}{12}$

$\frac{5}{8}$:x=$\frac{-2}{3}$

x=$\frac{5}{8}$:$\frac{-2}{3}$

x=$\frac{5}{8}$.$\frac{-3}{2}$

=-15/16
