Question

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

Answer 1

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

\(\Leftrightarrow\dfrac{11}{6}=\dfrac{-x}{5}\)

\(\Leftrightarrow x=\dfrac{-11\cdot5}{6}=\dfrac{-55}{6}\)

Answer 2

\(\dfrac{11}{6}=\dfrac{-x}{5}\)

\(55=-6x\)

\(\Rightarrow x=-\dfrac{55}{6}\)

Answer 3

\(1\dfrac{5}{6}=\dfrac{-x}{5}\\ \Rightarrow\dfrac{11}{6}=\dfrac{-x}{5}\\ \Rightarrow-6x=55\\ \Rightarrow x=\dfrac{-55}{6}\)

Vậy \(x=\dfrac{-55}{6}\)
