\(2x+\left|3-x\right|=x+1\)
\(\Leftrightarrow\left[{}\begin{matrix}2x+\left[-\left(3-x\right)\right]=x+1\\2x+\left(3-x\right)=x+1\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}2x-3+x=x+1\\2x+3-x=x+1\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=2\\0x=-2\left(vô.lí\right)\end{matrix}\right.\)
Vậy nghiệm của pt là \(S=\left\{2\right\}\)
