Ta có : \(\frac{x+2}{2019}+\frac{x+3}{2018}+\frac{x+4}{2017}+\frac{x+5}{1008}+\frac{x+2076}{11}=0\)
=> \(\frac{x+2}{2019}+1+\frac{x+3}{2018}+1+\frac{x+4}{2017}+1+\frac{x+5}{1008}+2+\frac{x+2076}{11}-5=0\)
=> \(\frac{x+2}{2019}+\frac{2019}{2019}+\frac{x+3}{2018}+\frac{2018}{2018}+\frac{x+4}{2017}+\frac{2017}{2017}+\frac{x+5}{1008}+\frac{2016}{1008}+\frac{x+2076}{11}-\frac{55}{11}=0\)
=> \(\frac{x+2021}{2019}+\frac{x+2021}{2018}+\frac{x+2021}{2017}+\frac{x+2021}{1008}+\frac{x+2021}{11}=0\)
=> \(\left(x+2021\right)\left(\frac{1}{2019}+\frac{1}{2018}+\frac{1}{2017}+\frac{1}{1008}+\frac{1}{11}\right)=0\)
=> \(x+2021=0\)
=> \(x=-2021\)
Vậy phương trình trên có tập nghiệm là \(S=\left\{-2021\right\}\)
