\(\dfrac{12}{7}:\dfrac{3}{14}=x:\dfrac{2}{5}\)

\(\Rightarrow8=x:\dfrac{2}{5}\)

\(\Rightarrow8.\dfrac{2}{5}=x\)

\(\Rightarrow\dfrac{16}{5}\)\(=x\)

Vậy \(x=\dfrac{16}{5}\)

\(8\dfrac{2}{3}:x-10=-8\)

\(\Rightarrow\dfrac{26}{3}:x=-8+10\)

\(\Rightarrow\dfrac{26}{3}:x=2\)

\(\Rightarrow x=\dfrac{26}{3}:2\)

\(\Rightarrow x=\dfrac{13}{3}\)

Vậy \(x=\dfrac{13}{3}\)

\(\dfrac{x}{3}=\dfrac{-10}{6}\)

\(\Leftrightarrow6x=-10.3\)

\(\Leftrightarrow6x=-30\)

\(\Leftrightarrow x=-30:6\)

\(\Leftrightarrow x=-5\)

Vậy \(x=-5\)
