\(\left|3x+2\right|-2-3x=0\)
\(\left|3x+2\right|=3x+2\)
\(\Rightarrow\left[{}\begin{matrix}3x+2=3x+2\\3x+2=-3x-2\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}\text{luôn đúng}\\6x=-4\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}\text{luôn đúng}\\x=\dfrac{-2}{3}\end{matrix}\right.\)
