 \(\frac{3}{7}-\frac{4}{7}:\left(x-1\right)=\frac{-5}{7}\)

\(\frac{4}{7}:\left(x-1\right)=\frac{3}{7}-\left(\frac{-5}{7}\right)=\frac{8}{7}\)

\(x-1=\frac{4}{7}:\frac{8}{7}\)

\(x-1=\frac{1}{2}\)

=> \(x=\frac{1}{2}+1=\frac{3}{2}\)

Vậy x= \(\frac{3}{2}\)
Chúc bạn học tốt !

\(\frac{3}{7}-\frac{4}{7}:\left(x-1\right)=-\frac{5}{7}\)

\(\Leftrightarrow\frac{4}{7}:\left(x-1\right)=\frac{3}{7}-\left(-\frac{5}{7}\right)\)

\(\Leftrightarrow\frac{4}{7}:\left(x-1\right)=\frac{8}{7}\)

\(\Leftrightarrow x-1=\frac{4}{7}:\frac{8}{7}\)

\(\Leftrightarrow x-1=\frac{1}{2}\)

\(\Leftrightarrow x=1\frac{1}{2}\)

Vậy: \(x=1\frac{1}{2}\)
