Question

\(\dfrac{3}{5}x-\dfrac{11}{5}=\dfrac{-3}{14}:\dfrac{5}{7}\)

nếu bài này có thể chuyển vế thì chuyển vế giúp mình luôn ạ, mình cảm ơnnn

 

 

Answer 1

\(\dfrac{3}{5}\)\(x\) - \(\dfrac{11}{5}\) = \(\dfrac{-3}{14}\) : \(\dfrac{5}{7}\) 

\(\dfrac{3}{5}\)\(x\) - \(\dfrac{11}{5}\) =  - \(\dfrac{3}{10}\)

\(\dfrac{3}{5}\)\(x\)         = - \(\dfrac{3}{10}\) + \(\dfrac{11}{5}\)

\(\dfrac{3}{5}\)\(x\)       = \(\dfrac{19}{10}\) 

\(x\)         = \(\dfrac{19}{10}\) : \(\dfrac{3}{5}\)

\(x\)        = \(\dfrac{19}{6}\)

 

Answer 2

\(\dfrac{3}{5}x-\dfrac{11}{5}=-\dfrac{3}{14}:\dfrac{5}{7}\)

\(\Rightarrow\dfrac{3}{5}x-\dfrac{11}{5}=-\dfrac{3}{14}\cdot\dfrac{7}{5}\)

\(\Rightarrow\dfrac{3}{5}x-\dfrac{11}{5}=-\dfrac{3}{10}\)

\(\Rightarrow\dfrac{3}{5}x=-\dfrac{3}{10}+\dfrac{11}{5}\)

\(\Rightarrow\dfrac{3}{5}x=\dfrac{19}{10}\)

\(\Rightarrow x=\dfrac{19}{10}:\dfrac{3}{5}\)

\(\Rightarrow x=\dfrac{19}{6}\)
