mk nghĩ đề sai đó bạn
\(\frac{x-11}{2000}+\frac{x+5}{2016}+\frac{x+1}{1006}=4\)
\(\Leftrightarrow\left(\frac{x-11}{2000}-1\right)+\left(\frac{x+5}{2016}-1\right)+\left(\frac{x+1}{1006}-2\right)=0\)
\(\Leftrightarrow\frac{x-2011}{2000}+\frac{x-2011}{2016}+\frac{x-2011}{1006}=0\)
\(\Leftrightarrow\left(x-2011\right)\left(\frac{1}{2000}+\frac{1}{2016}+\frac{1}{1006}\right)=0\)
\(\Rightarrow x-2011=0\Rightarrow x=2011\)
