`2x+3=|3x-2|(x>=-2/3)`
`<=>` $\left[ \begin{array}{l}2x+3=3x-2\\2x+3=2-3x\end{array} \right.$
`<=>` $\left[ \begin{array}{l}x=5(tm)\\5x=-1\end{array} \right.$
`<=>` $\left[ \begin{array}{l}x=5\\x=-\dfrac15(tm)\end{array} \right.$
Vậy `S={5,-1/5}`
2x+3=3x-2
(=) 2x-3x=| -2-3|
(=) -x = 5
x = -1\5
S(-1/5)
