mk hoàn toàn k biết

a) \(\left|2x-3\right|-\dfrac{5}{2}=\dfrac{1}{3}\)

\(\left|2x-3\right|=\dfrac{1}{3}+\dfrac{5}{2}=\dfrac{2}{6}+\dfrac{15}{6}\)

\(\left|2x-3\right|=\dfrac{17}{6}\)

\(+)2x-3=\dfrac{17}{6}\Rightarrow2x=\dfrac{35}{6}\Rightarrow x=\dfrac{35}{12}\)

\(+)2x-3=\dfrac{-17}{6}\Rightarrow2x=\dfrac{1}{6}\Rightarrow x=\dfrac{1}{12}\)

vậy...
