Em làm thế đúng không các anh chị?
đúng đó nhưng bạn nên nhóm \(\frac{-22}{3}\)và \(\frac{-5}{3}\)vào với nhau và đặt \(\frac{5}{9}\)ra ngoài sẽ tính nhanh hơn

\(-\frac{5}{12}:\left(\frac{11}{4}x-\frac{3}{4}\right)=\frac{22}{9}\)
\(\frac{-5}{12}:\left(\frac{11}{4}x-\frac{3}{4}\right)=\frac{22}{9}\)
\(\Rightarrow\frac{11}{4}x-\frac{3}{4}=\frac{-5}{12}:\frac{22}{9}\)
\(\Rightarrow\frac{11}{4}x=\frac{-15}{88}+\frac{3}{4}\)
\(\Rightarrow x=\frac{51}{88}:\frac{11}{4}=\frac{51}{242}\)
Vậy \(x=\frac{51}{242}\)
