a) Xét \(x\ge2\)
\(\Rightarrow x-2+2x-3=2x+1\)
\(\Leftrightarrow3x-5=2x+1\)
\(\Leftrightarrow x=6\left(tm\right)\)
Xét \(\dfrac{3}{2}\le x< 2\)
\(\Rightarrow2-x+2x-3=2x+1\)
\(\Leftrightarrow x-1=2x+1\)
\(\Leftrightarrow x=-2\)(loại)
Xét \(x\le\dfrac{3}{2}\)
\(\Rightarrow2-x+3-2x=2x+1\)
\(\Leftrightarrow5-3x=2x+1\)
\(\Leftrightarrow x=\dfrac{4}{5}\left(tm\right)\)
Vậy .....
