Answer 2

\(\left\{\begin{matrix}\left|x-2011y\right|\ge0\\\left(y-1\right)^{2012}\ge0\end{matrix}\right.\Rightarrow\left\{\begin{matrix}x-2011y=0\\y-1=0\end{matrix}\right.\)

\(\Rightarrow\left\{\begin{matrix}x-2011y=0\\y=1\end{matrix}\right.\Rightarrow\left\{\begin{matrix}x-2011=0\Rightarrow x=2011\\y=1\end{matrix}\right.\)
