\(\frac{11}{12}-\frac{2}{3}\left|x\right|=\frac{3}{8}\)
\(\Leftrightarrow\frac{2}{3}\left|x\right|=\frac{13}{24}\)
\(\Leftrightarrow\left|x\right|=\frac{13}{16}\)
\(\Leftrightarrow\orbr{\begin{cases}x=\frac{13}{16}\\x=-\frac{13}{16}\end{cases}}\)
Ta có \(\frac{11}{12}-\frac{2}{3}.\left|x\right|=\frac{3}{8}\)
\(\Leftrightarrow\frac{2}{3}.\left|x\right|=\frac{11}{12}-\frac{3}{8}\)
\(\Leftrightarrow\frac{2}{3}\left|x\right|=\frac{22}{24}-\frac{9}{24}\)
\(\Leftrightarrow\frac{2}{3}\left|x\right|=\frac{13}{24}\)
\(\Leftrightarrow\left|x\right|=\frac{13}{16}\)
\(\Leftrightarrow x=\pm\frac{13}{16}\)
Vậy \(x=\pm\frac{13}{16}\)
