Question

\(\dfrac{-6}{5}\)x +\(\dfrac{1}{4}\)=\(\dfrac{2}{5}\)

giúp mình với ạ

Answer 1

Đề sai hay gì rồi

Answer 2

\(-\dfrac{6}{5}x+\dfrac{1}{4}=\dfrac{2}{5}\\ \Leftrightarrow-\dfrac{6}{5}x=\dfrac{2}{5}-\dfrac{1}{4}=\dfrac{8}{20}-\dfrac{5}{20}=\dfrac{3}{20}\\ \Leftrightarrow x=\dfrac{3}{20}:\left(-\dfrac{6}{5}\right)=-\dfrac{1}{8}\)
