Đáp án:

|X-( $\frac{1}{4}$ : $\frac{1}{2}$ . $\frac{1}{3}$ )|= (5- $\frac{1}{3}$ ): $\frac{2}{3}$

|X- $\frac{1}{6}$ |= $\frac{14}{3}$ : $\frac{2}{3}$

|X- $\frac{1}{6}$ |=7

X- $\frac{1}{6}$ =-7 hoặc X- $\frac{1}{6}$ =7

X = (-7)+ $\frac{1}{6}$ X = 7+ $\frac{1}{6}$

X = $\frac{- 41}{6}$ X = $\frac{41}{6}$

=> X ∈ { $\frac{- 41}{6}$ ; $\frac{41}{6}$ }

Cho mình xin ctlhn nha
