THANHKIU Ạ

Answer 1

\(\left|x-12\right|=2014\\ \Rightarrow\left[{}\begin{matrix}x-12=2014\\x-12=-2014\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=2014+12\\x=-2014+12\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=2026\\x=-2002\end{matrix}\right.\)

Vậy \(x\in\left\{2014;-2002\right\}\)

Answer 2

\(\left|x-12\right|=2014\\ \Rightarrow\left\{{}\begin{matrix}x-12=2014\\x-12=-2014\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=2026\\x=-2002\end{matrix}\right.\)

Vậy...
