\(a,\dfrac{3}{4}\cdot\left(\dfrac{1}{2}\cdot x-1\right)-\dfrac{1}{4}=-\dfrac{1}{4}\)

\(\xrightarrow[]{}\dfrac{3}{4}\cdot\left(\dfrac{1}{2}\cdot x-1\right)=-\dfrac{1}{4}+\dfrac{1}{4}\)

\(\xrightarrow[]{}\dfrac{1}{2}\cdot x-1=0:\dfrac{3}{4}\)

\(b,1\dfrac{2}{5}-\dfrac{2}{5}\cdot\left(x+\dfrac{1}{2}\right)=\dfrac{2}{5}\)

\(\xrightarrow[]{}\dfrac{7}{5}-\dfrac{2}{5}\cdot\left(x+\dfrac{1}{2}\right)=\dfrac{2}{5}\)

\(\xrightarrow[]{}\dfrac{2}{5}\cdot\left(x+\dfrac{1}{2}\right)=\dfrac{7}{5}-\dfrac{2}{5}\)

\(a)\) \(0,5+\dfrac{1}{3}+0,4+\dfrac{5}{7}+\dfrac{1}{6}-\dfrac{4}{35}\)

\(=\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{2}{5}+\dfrac{5}{7}+\dfrac{1}{6}-\dfrac{4}{35}\)

\(=\left(\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{6}\right)+\left(\dfrac{2}{5}+\dfrac{5}{7}-\dfrac{4}{35}\right)\)

\(=1+1=2\)

\(b)\) \(\dfrac{1}{3}\cdot\dfrac{-5}{9}+\dfrac{1}{3}\cdot\dfrac{-1}{9}+4\dfrac{1}{3}\cdot\dfrac{1}{9}\)
 

\(=\dfrac{1}{3}\cdot\dfrac{-5}{9}+\dfrac{1}{3}\cdot\dfrac{-1}{9}+\dfrac{13}{3}\cdot\dfrac{1}{9}\)

\(=\dfrac{-5}{27}+\left[\dfrac{1}{9}\cdot\left(-\dfrac{1}{3}+\dfrac{13}{3}\right)\right]\)
 

\(=\dfrac{-5}{27}+\left[\dfrac{1}{9}\cdot4\right]\)

\(=\dfrac{-5}{27}+\dfrac{4}{9}=\dfrac{7}{27}\)
