Question

\(\frac{4}{5}x-\frac{3}{10}x=-1\frac{1}{5}\)

Thank you so much!!!

Answer 1

\(\frac{4}{5}x-\frac{3}{10}x=-1\frac{1}{5}\\ x\cdot\left(\frac{4}{5}-\frac{3}{10}\right)=\frac{-6}{5}\\ x\left(\frac{8}{10}-\frac{3}{10}\right)=\frac{-6}{5}\\ x\cdot\frac{1}{2}=\frac{-6}{5}\\ x=\frac{-6}{5}:\frac{1}{2}\\ x=\frac{-6}{5}\cdot2\\ x=\frac{-12}{5}\)Vậy \(x=\frac{-12}{5}\)

Answer 2

\(\frac{4}{5}x-\frac{3}{10}x=-1\frac{1}{5}\)

\(\frac{8}{10}x-\frac{3}{10}x=\frac{-6}{5}\)

\(\frac{5}{10}x=\frac{-6}{5}\)

\(\frac{1}{2}x=\frac{-6}{5}\)

\(x=\frac{-6}{5}:\frac{1}{2}\)

\(x=\frac{-6}{5}\cdot2\)

\(x=\frac{-12}{5}\)
