(x-\(\frac{1}{3}\)).(\(\frac{1}{2}-\frac{2}{5}-\frac{5}{6}\))-\(\frac{1}{2}\)=\(\frac{3}{10}-\frac{1}{4}\)
\(\Rightarrow\left(x-\frac{1}{3}\right)\left(\frac{15}{30}-\frac{12}{30}-\frac{25}{30}\right)-\frac{1}{2}=\frac{1}{20}\)
\(\Rightarrow\left(x-\frac{1}{3}\right)\left(-\frac{11}{15}\right)=\frac{11}{20}\)
\(\Rightarrow x-\frac{1}{3}=-\frac{3}{4}\)
\(\Rightarrow x=-\frac{5}{12}\)
