Question

Tìm x :x/3 -1/4=-5/6

Answer 1

-7/12

 

Answer 2

\(\dfrac{x}{3}-\dfrac{1}{4}=\dfrac{-5}{6}\) 

        \(\dfrac{x}{3}=\dfrac{-5}{6}+\dfrac{1}{4}\) 

        \(\dfrac{x}{3}=\dfrac{-7}{12}\) 

\(\Rightarrow x.12=3.-7\) 

     \(x.12=-21\) 

         \(x=-21:12\) 

         \(x=\dfrac{-7}{4}\)
