Question

\(\frac{-4}{7}-x=\frac{3}{5}-2x\)

giúp mình vs

Answer 1

\(\frac{-4}{7}-x=\frac{3}{5}-2x\)

\(-\frac{4}{7}=\frac{3}{5}-\left(2x-x\right)\)

\(\frac{-4}{7}=\frac{3}{5}-x\)

\(x=\frac{3}{5}+\frac{-4}{7}\)

\(x=\frac{1}{35}\)

Vậy \(x=\frac{1}{35}\)

 

Answer 2

\(-\frac{4}{7}-x=\frac{3}{5}-2x\\ =>-\frac{4}{7}-\frac{3}{5}\\=-2x+x\\ =>-\frac{41}{35}=-x\\ =>x=\frac{41}{35}\)
