\(\frac{3}{7}-\frac{4}{7}:\left(x-1\right)=\frac{-5}{7}\)
\(\frac{4}{7}:\left(x-1\right)=\frac{3}{7}-\left(\frac{-5}{7}\right)=\frac{8}{7}\)
\(x-1=\frac{4}{7}:\frac{8}{7}\)
\(x-1=\frac{1}{2}\)
=> \(x=\frac{1}{2}+1=\frac{3}{2}\)
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: \(x=1\frac{1}{2}\)
