Question

0,6x - 1/3x = 4/9

Answer 1

\(0,6x-\dfrac{1}{3}x=\dfrac{4}{9}x\Leftrightarrow\dfrac{4}{15}x=\dfrac{4}{9}\Rightarrow x=\dfrac{5}{3}\)

Answer 2

\(0,6x-\dfrac{1}{3}x=\dfrac{4}{9}\)

\(\Leftrightarrow x\left(\dfrac{3}{5}-\dfrac{1}{3}\right)=\dfrac{4}{9}\)

\(\Leftrightarrow x.\dfrac{4}{15}=\dfrac{4}{9}\Rightarrow x=\dfrac{4}{9}:\dfrac{4}{15}=\dfrac{5}{3}\)

Answer 3

\(0,6x-\dfrac{1}{3}x=\dfrac{4}{9}\) 

\(x.\left(\dfrac{3}{5}-\dfrac{1}{3}\right)=\dfrac{4}{9}\) 

          \(x.\dfrac{4}{15}=\dfrac{4}{9}\) 

                \(x=\dfrac{4}{9}:\dfrac{4}{15}\) 

                \(x=\dfrac{5}{3}\)
