Question

\(\frac{x}{5}\)-\(\frac{5}{2}\)=-31

Answer 1

\(\frac{x}{5}-\frac{5}{2}=-31\)

\(=>\frac{x}{5}=-31+\frac{5}{2}\)

\(\frac{x}{5}=-28,5\)

\(=>x=-28,5\cdot5\)

\(=>x=-142,5\)

Vậy x = -142, 5

 

Answer 2

\(\frac{x}{5}-\frac{5}{2}=-31\)

\(\Rightarrow\frac{x}{5}-2,5=-31\)

\(\Rightarrow\frac{x}{5}=-31+2,5\)

\(\Rightarrow\frac{x}{5}=-28,5\)

\(\Rightarrow x=-142,5\)

Vậy \(x=-142,5\)
