\(x-\dfrac{3}{5}=\dfrac{2}{3}\times\dfrac{1}{5}\\ \Rightarrow x-\dfrac{3}{5}=\dfrac{2}{15}\\ \Rightarrow x=\dfrac{2}{15}+\dfrac{3}{5}\\ \Rightarrow x=\dfrac{2}{15}+\dfrac{9}{15}\\ \Rightarrow x=\dfrac{11}{15}\)

\(x:\dfrac{4}{7}=\dfrac{6}{7}-\dfrac{1}{3}\\ \Rightarrow x:\dfrac{4}{7}=\dfrac{18}{21}-\dfrac{7}{21}\\ \Rightarrow x:\dfrac{4}{7}=\dfrac{11}{21}\\ \Rightarrow x=\dfrac{11}{21}\times\dfrac{4}{7}\\ \Rightarrow x=\dfrac{44}{147}\)
\(x\div\dfrac{4}{7}=\dfrac{6}{7}-\dfrac{1}{3}\)
\(x\div\dfrac{4}{7}=\dfrac{11}{21}\)
\(x=\dfrac{11}{21}\times\dfrac{4}{7}\)
\(x=\dfrac{44}{147}\)
