Đáp án:

$\text{x = $\dfrac{-1}{12}$}$

Giải thích các bước giải:

$\text{($\dfrac{-3}{8}$ + $\dfrac{1}{4}$) : x - $\dfrac{1}{6}$ = $\dfrac{4}{3}$}$

$\text{⇒ ($\dfrac{-3}{8}$ + $\dfrac{2}{8}$) : x - $\dfrac{1}{6}$ = $\dfrac{4}{3}$}$

$\text{⇒ $\dfrac{-1}{8}$ : x - $\dfrac{1}{6}$ = $\dfrac{4}{3}$}$

$\text{⇒ $\dfrac{-1}{8}$ : x = $\dfrac{4}{3}$ + $\dfrac{1}{6}$}$

$\text{⇒ $\dfrac{-1}{8}$ : x = $\dfrac{8}{6}$ + $\dfrac{1}{6}$}$

$\text{⇒ $\dfrac{-1}{8}$ : x = $\dfrac{9}{6}$ = $\dfrac{3}{2}$}$

$\text{⇒ x = $\dfrac{-1}{8}$ : $\dfrac{3}{2}$}$

$\text{⇒ x = $\dfrac{-1}{12}$}$

$\text{Vậy x = $\dfrac{-1}{12}$}$

`(-3/8+1/4):x-1/6=4/3`

`=> -1/8:x-1/6=4/3`

`=> -1/8:x=3/2`

`=> x=-1/8:3/2`

`=> x=-1/12`

Vậy `x=-1/12`
