\(3\cdot2\cdot x-\left(\dfrac{4}{5}+\dfrac{2}{3}\right):\dfrac{11}{3}=\dfrac{7}{20}\)
\(6x-\left(\dfrac{12}{15}+\dfrac{10}{15}\right)\cdot\dfrac{3}{11}=\dfrac{7}{20}\)
\(6x-\dfrac{22}{15}\cdot\dfrac{3}{11}=\dfrac{7}{20}\\ 6x-\dfrac{2}{5}=\dfrac{7}{20}\\ 6x=\dfrac{7}{20}+\dfrac{2}{5}\\ 6x=\dfrac{3}{4}\\ x=\dfrac{1}{8}\)
\(3.2x-\left(\dfrac{4}{5}+\dfrac{2}{3}\right):\dfrac{11}{3}=\dfrac{7}{20}\)
\(\Rightarrow6x-\dfrac{22}{15}:\dfrac{11}{3}=\dfrac{7}{20}\)
\(\Rightarrow6x-\dfrac{2}{5}=\dfrac{7}{20}\)
\(\Rightarrow6x=\dfrac{7}{20}+\dfrac{2}{5}\)
\(\Rightarrow6x=\dfrac{3}{4}\)
\(\Rightarrow x=\dfrac{3}{4}:6\)
\(\Rightarrow x=\dfrac{1}{8}\)
