\(3\dfrac{1}{4}-\left(2\dfrac{1}{2}x-1\dfrac{1}{3}\right)=1\dfrac{1}{2}:\left(-\dfrac{1}{6}\right)\)
\(\dfrac{13}{4}-\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=\dfrac{3}{2}:\left(-\dfrac{1}{6}\right)\)
\(\dfrac{13}{4}-\dfrac{5}{2}x+\dfrac{4}{3}=-9\)
\(-\dfrac{5}{2}x=-9-\dfrac{4}{3}-\dfrac{13}{4}\)
\(-\dfrac{5}{2}x=-\dfrac{163}{12}\)
\(\Rightarrow\dfrac{5}{2}x=\dfrac{163}{12}\)
\(\Rightarrow x=\dfrac{163}{12}:\dfrac{5}{2}\)
\(\Rightarrow x=\dfrac{163}{30}\)
\(3\dfrac{1}{4}-\left(2\dfrac{1}{2}x-1\dfrac{1}{3}\right)=1\dfrac{1}{2}:\left(-\dfrac{1}{6}\right)\)
\(\dfrac{13}{4}-\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=\dfrac{3}{2}:-\dfrac{1}{6}\)
\(\dfrac{13}{4}-\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=-9\)
\(\dfrac{5}{2}x-\dfrac{4}{3}=\dfrac{13}{4}-\left(-9\right)\)
\(\dfrac{5}{2}x-\dfrac{4}{3}=\dfrac{49}{4}\)
\(\dfrac{5}{2}x=\dfrac{49}{4}+\dfrac{4}{3}\)
\(\dfrac{5}{2}x=\dfrac{163}{12}\)
\(x=\dfrac{163}{12}:\dfrac{5}{2}\)
\(x=\dfrac{163}{30}\)

\(3\dfrac{1}{4}-\left(2\dfrac{1}{2}x-1\dfrac{1}{3}\right)=1\dfrac{1}{2}:\left(-\dfrac{1}{6}\right)\\ < =>\dfrac{13}{4}-\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=\dfrac{3}{2}.\left(-6\right)\\ < =>\dfrac{13}{4}-\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=-9\\ < =>\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=\dfrac{13}{4}-\left(-9\right)\\ < =>\left(\dfrac{5}{2}x-\dfrac{4}{3}\right)=\dfrac{49}{4}\\< =>\dfrac{5}{2}x=\dfrac{49}{4}+\dfrac{4}{3}=\dfrac{163}{12}\\ =>x=\dfrac{163}{12}:\dfrac{5}{2}=\dfrac{163}{30}=5\dfrac{13}{30}\)
13\4-(5\2x-4\3)=3\2:(-1\6)
13\4-(5\2x-4\3)=-9
5\2x-4\3=-9+13\4=-23\4
5\2x=-23\4+4\3=-53\12
x=-53\12:5\2=-53\30
