Question

/x-2/=x đề bài là tìm x nha mn giải hộ mik nhanh giúp ạ

Answer 1

\(\left|x-2\right|=x\)

\(\Leftrightarrow\left[{}\begin{matrix}x-2=x\\x-2=-x\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x-x=2\\x+x=2\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x\in\varnothing\\2x=2\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x\in\varnothing\\x=1\end{matrix}\right.\)

Vậy \(x=1\)
