Answer 1

\(\dfrac{11}{12}-\left(\dfrac{2}{5}-\dfrac{3}{4}x\right)=\dfrac{2}{3}\)

\(\dfrac{2}{5}-\dfrac{3}{4}x=\dfrac{11}{12}-\dfrac{2}{3}\)

\(\dfrac{2}{5}-\dfrac{3}{4}x=\dfrac{1}{4}\)

\(\dfrac{3}{4}x=\dfrac{2}{5}-\dfrac{1}{4}\)

\(\dfrac{3}{4}x=\dfrac{3}{20}\)

\(x=\dfrac{3}{20}:\dfrac{3}{4}\)

=> \(x=\dfrac{1}{5}\)

Answer 2

\(\dfrac{11}{12}\)- (\(\dfrac{2}{5}-\dfrac{3}{4}\)x ) = \(\dfrac{2}{3}\)

\(\dfrac{2}{5}-\dfrac{3}{4}\)x = \(\dfrac{11}{12}\)- \(\dfrac{2}{3}\)

\(\dfrac{2}{5}-\dfrac{3}{4}\)x = \(\dfrac{1}{4}\)

\(\dfrac{3}{4}\)x = \(\dfrac{2}{5}\)- \(\dfrac{1}{4}\)

\(\dfrac{3}{4}\)x = \(\dfrac{3}{20}\)

x = \(\dfrac{3}{20}\): \(\dfrac{3}{4}\)

x= \(\dfrac{1}{5}\)
