$$\begin{gathered} \frac{\mathrm{x}+1}{2009}+\frac{x+2}{2008}+\frac{x+17}{1993}+3=0 \\ \frac{x-4}{96}+\frac{x-7}{93}+\frac{x-8}{92}+\frac{x-10}{90}+\frac{x-15}{85}=5 \\ \frac{x-3}{97}-\frac{x-5}{93}-\frac{x-9}{91}=\frac{x-91}{9}-\frac{x-92}{8}-\frac{x-61}{39} \\ \frac{x-120}{3}-\frac{x-119}{4}-\frac{x-100}{23}=\frac{x-5}{118}-\frac{x-6}{117}-\frac{x-23}{100} \end{gathered}$$
