Question

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

Answer 1

`∣2x-5/6∣=1`

\(\Rightarrow\left[{}\begin{matrix}2x-\dfrac{5}{6}=1\\2x-\dfrac{5}{6}=-1\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}2x=\dfrac{11}{6}\\2x=\dfrac{-1}{6}\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=\dfrac{11}{12}\\x=-\dfrac{1}{12}\end{matrix}\right.\)

Answer 2

=>2x-5/6=1 hoặc 2x-5/6=-1

=>x=11/12 hoặc x=-1/12
