\(\dfrac{11}{12}-\left(\dfrac{2}{5}+x\right)=\dfrac{2}{3}\left(6x+1\right)\)
\(\Rightarrow\dfrac{11}{12}-\dfrac{2}{5}-x=4x+\dfrac{2}{3}\)
\(\Rightarrow-x-4x=-\dfrac{11}{12}+\dfrac{2}{5}+\dfrac{2}{3}\)
\(\Rightarrow-5x=\dfrac{3}{20}\)
\(\Rightarrow x=\dfrac{3}{20}:\left(-5\right)=-0,03\)
\(\dfrac{11}{12}-\left(\dfrac{2}{5}+x\right)=\dfrac{2}{3}.\left(6x+1\right)\)
\(\dfrac{11}{12}-\dfrac{2}{5}-x=4x+\dfrac{2}{3}\)
\(-x-4x=\dfrac{2}{3}-\dfrac{11}{12}+\dfrac{2}{5}\)
\(-5x=\dfrac{3}{20}\)
\(x=-\dfrac{3}{100}\)
\(\dfrac{11}{12}-\left(\dfrac{2}{5}+x\right)=\dfrac{2}{3}\left(6x+1\right)\)
\(\dfrac{11}{12}-\dfrac{2}{5}-x=4x+\dfrac{2}{3}\)
\(4x+\dfrac{2}{5}=\dfrac{31}{60}-x\)
\(5x=\dfrac{7}{60}\)
\(x=\dfrac{7}{300}\)
