\(\left|x-1\right|=2011\)
\(\Rightarrow\left[{}\begin{matrix}x-1=2011\\x-1=-2011\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=2012\\x=-2010\end{matrix}\right.\)
| x - 1 | = 2011
=> \(\left[{}\begin{matrix}x-1=2011\\x-1=-2011\end{matrix}\right.\)
=> \(\left[{}\begin{matrix}x=2011+1\\x=-2011+1\end{matrix}\right.\)
=> \(\left[{}\begin{matrix}x=2012\\x=-2010\end{matrix}\right.\)
|x-1|=2011
=>x-1=2011 =>x=2011+1 =>x=2012
x-1=-2011 x=-2011+1 x=-2010
Vay x=2012 hoac x=-2010
Tick cho minh nhe
\(\Rightarrow x-1=2011\)\(\Rightarrow x=2011+1=2012\)
\(\Rightarrow x-1=-2011\Rightarrow x=-2011+1=-2010\)
cảm ơn...cảm ơn các bn rất nhìu... mk thật sự rất cảm ơn
=> x -1 = 2011 => x = 2012
=>x - 1 = -2011 => x = -2010
Vậy x = 2012 và -2010
