\(\left|x+\dfrac{2009}{2010}\right|-\dfrac{1}{2010}=0\)
\(\Rightarrow\left|x+\dfrac{2009}{2010}\right|=\dfrac{1}{2010}\)
\(\Rightarrow\left[{}\begin{matrix}x+\dfrac{2009}{2010}=\dfrac{1}{2010}\Rightarrow x=\dfrac{-1004}{1005}\\x+\dfrac{2009}{2010}=\dfrac{-1}{2010}\Rightarrow x=-1\end{matrix}\right.\)
