\(x+\left|\dfrac{1}{2}-\dfrac{1}{3}\right|=\left|\dfrac{-2}{3}-\dfrac{1}{4}\right|\)
\(x+\left|\dfrac{1}{6}\right|=\left|\dfrac{-11}{12}\right|\)
\(x+\dfrac{1}{6}=\dfrac{11}{12}\)
\(x=\dfrac{11}{12}-\dfrac{1}{6}\)
\(x=\dfrac{3}{4}\)
Vậy ...
BT3: Tìm x, biết
15) \(2\text{|}\dfrac{1}{2}x-\dfrac{1}{3}\text{|}-\dfrac{3}{2}=\dfrac{1}{4}\)
16) \(\dfrac{3}{4}-2.\text{|}2x-\dfrac{2}{3}\text{|}=2\)
