Question

|1/2x|=3-2x

Answer 1

\(\left|\dfrac{1}{2}x\right|=3-2x\)(\(x\le\dfrac{3}{2}\))

\(\Rightarrow\dfrac{1}{2}x=3-2x\)           \(\dfrac{1}{2}x=-3+2x\)

\(\Rightarrow\dfrac{5}{2}x=3\)                     \(\Rightarrow\dfrac{-3}{2}x=-3\)

\(\Rightarrow x=\dfrac{6}{5}\)   (Tm)          \(\Rightarrow x=2\)(loại)

Vậy    \(x=\dfrac{6}{5}\)
