\(\frac{13}{20}+\left(\frac{3}{5}+x\right)=\frac{5}{6}\)
\(\Rightarrow\frac{3}{5}+x=\frac{11}{60}\)
\(\Rightarrow x=-\frac{5}{12}\)
\(\frac{2}{5}+\frac{3}{5}:x=-3\)
\(\Rightarrow\frac{3}{5}:x=-\frac{17}{5}\)
\(\Rightarrow x=\frac{3}{5}:-\frac{17}{5}\)
\(\Rightarrow x=\frac{3}{-17}\)

\(\frac{13}{20}+\left(\frac{3}{5}+x\right)=\frac{5}{6}\)
\(\frac{3}{5}+x=\frac{5}{6}-\frac{13}{20}\)
\(\frac{3}{5}+x=\frac{11}{60}\)
\(x=\frac{11}{60}-\frac{3}{5}\)
\(x=-\frac{5}{12}\)
\(\frac{2}{5}+\frac{3}{5} :x=-3\)
\(\frac{3}{5}:x=-3-\frac{2}{5}\)
\(\frac{3}{5}:x=-\frac{17}{5}\)
\(x=\frac{3}{5}:\left(-\frac{17}{5}\right)\)
\(x=-\frac{3}{17}\)
