a) ĐKXĐ: \(x\ne0\)
\(\Rightarrow-\dfrac{3}{4}:x=-\dfrac{11}{36}+\dfrac{1}{4}=-\dfrac{1}{18}\Rightarrow x=\left(-\dfrac{3}{4}\right):\left(-\dfrac{1}{18}\right)=\dfrac{27}{2}\left(tm\right)\)
b) ĐKXĐ: \(x\ne0\)
\(\Rightarrow\left(\dfrac{13}{4}:x\right).\left(-\dfrac{5}{4}\right)=-\dfrac{5}{2}\Rightarrow\left(\dfrac{13}{4}:x\right)=\left(-\dfrac{5}{2}\right):\left(-\dfrac{5}{4}\right)=2\Rightarrow x=\dfrac{13}{4}:2=\dfrac{13}{8}\left(tm\right)\)
c) \(\Rightarrow\left[{}\begin{matrix}2x-3=0\\x=0\\x-\dfrac{2}{3}=0\end{matrix}\right.\)\(\Rightarrow\left[{}\begin{matrix}x=\dfrac{3}{2}\\x=0\\x=\dfrac{2}{3}\end{matrix}\right.\)
