Answer 1

Đề : Tìm x???

\(\frac{2}{3}x+\frac{1}{4}x=\frac{-22}{27}\)

\(x\left(\frac{2}{3}+\frac{1}{4}\right)=\frac{-22}{27}\)

\(x\left(\frac{8}{12}+\frac{3}{12}\right)=\frac{-22}{27}\)

\(x.\frac{11}{12}=\frac{-22}{27}\)

\(x=\frac{-22}{27}\div\frac{11}{12}\)

\(x=\frac{-22}{27}.\frac{12}{11}\)

\(x=\frac{-8}{9}\)

Vậy \(x=-\frac{8}{9}\).
