\(\left|\dfrac{1}{2}x\right|=3-2x\)(1)
Vì \(VT\ge0\Rightarrow3-2x\ge0\Leftrightarrow x\le\dfrac{3}{2}\)
\(\left(1\right)\Leftrightarrow\left[{}\begin{matrix}\dfrac{1}{2}x=3-2x\\\dfrac{1}{2}x=-3+2x\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{6}{5}\left(Chon\right)\\x=2\left(Loai\right)\end{matrix}\right.\)
Vậy....
