`2/3 (X - 25%) = 1/6` NHanhhhh

Đáp án:

 $\dfrac{2}{3}.(x-$ $\text{25%}$ $)= \dfrac{1}{6}$

$⇒ x- \dfrac{1}{4}= \dfrac{1}{6}:\dfrac{2}{3}$

$⇒ x-\dfrac{1}{4}= \dfrac{1}{6}.\dfrac{3}{2}$

$⇒ x- \dfrac{1}{4}= \dfrac{1}{4}$

$⇒ x= \dfrac{1}{4}+\dfrac{1}{4}$

$⇒x= \dfrac{2}{4}$

$⇒ x= \dfrac{1}{2}$

$\text{Vậy x=$\dfrac{1}{2}$}$
