2⋅|x 1|- 1/2 = 1/3

Lời giải:

|2x – 1| - \(\frac{1}{2} = \frac{1}{3}\)

\[\begin{array}{l}\left| {2x - 1} \right| = \frac{1}{3} + \frac{1}{2}\\\left| {2x - 1} \right| = \frac{5}{6}\end{array}\]

\[2x - 1 = \frac{5}{6}\] hoặc \[2x - 1 =  - \frac{5}{6}\]

\[2x = \frac{{11}}{6}\] hoặc \[2x = \frac{1}{6}\]

\[x = \frac{{11}}{{12}}\] hoặc \[x = \frac{1}{{12}}\].
