\(\dfrac{1}{3}-\left(\dfrac{1}{2}x+\dfrac{1}{4}\right)=\dfrac{7}{6}\)
\(\Rightarrow-\dfrac{1}{2}x=\dfrac{14}{12}-\dfrac{4}{12}+\dfrac{3}{12}\)
\(\Rightarrow-\dfrac{1}{2}x=\dfrac{13}{12}\)
\(\Rightarrow x=\dfrac{13\cdot\left(-2\right)}{12}=-\dfrac{26}{12}=-\dfrac{13}{6}\)
\(\dfrac{1}{3}-\left(\dfrac{1}{2}x+\dfrac{1}{4}\right)=\dfrac{7}{6}\)
\(=>\dfrac{1}{2}x+\dfrac{1}{4}=\dfrac{1}{3}-\dfrac{7}{6}\)
\(=>\dfrac{1}{2}x+\dfrac{1}{4}=-\dfrac{5}{6}\)
\(=>\dfrac{1}{2}x=-\dfrac{5}{6}-\dfrac{1}{4}\)
\(=>\dfrac{1}{2}x=-\dfrac{13}{12}\)
\(=>x=\dfrac{13}{12}:\dfrac{1}{2}\)
\(=>x=-\dfrac{13}{6}\)
