$\text{|x - $\dfrac{1}{2}$| = $\dfrac{6}{3}$.}$
$\text{|x - $\dfrac{1}{2}$| = 2.}$
$\text{⇒ x - $\dfrac{1}{2}$ = 2 hoặc x - $\dfrac{1}{2}$ = -2.}$
$\text{* Trường hợp 1:}$
$\text{x - $\dfrac{1}{2}$ = 2.}$
$\text{⇒ x = 2 + $\dfrac{1}{2}$.}$
$\text{⇒ x = $\dfrac{4}{2}$ + $\dfrac{1}{2}$.}$
$\text{⇒ x = $\dfrac{5}{2}$.}$
$\text{* Trường hợp 2:}$
$\text{x - $\dfrac{1}{2}$ = -2.}$
$\text{⇒ x = -2 + $\dfrac{1}{2}$.}$
$\text{⇒ x = $\dfrac{-4}{2}$ + $\dfrac{1}{2}$.}$
$\text{⇒ x = $\dfrac{-3}{2}$.}$
$\text{Vậy x = $\dfrac{5}{2}$ hoặc x = $\dfrac{-3}{2}$.}$
