(1\4-2\3):3x\5=5\2
giúp tôi câu này với sú
\(\left(\dfrac{1}{4}-\dfrac{2}{3}\right):\dfrac{3x}{5}=\dfrac{5}{2}\Leftrightarrow\dfrac{-5}{12}:\dfrac{3x}{5}=\dfrac{5}{2}\Leftrightarrow\dfrac{3x}{5}=-\dfrac{1}{6}\Leftrightarrow x=-\dfrac{5}{18}\)
\(\left(\dfrac{1}{4}-\dfrac{2}{3}\right):\dfrac{3x}{5}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{-5}{12}:\dfrac{3x}{5}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{3x}{5}=\dfrac{-5}{12}:\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{3x}{5}=\dfrac{-1}{6}\)
\(\Leftrightarrow x=\dfrac{-1}{6}:\dfrac{3}{5}\)
\(\Leftrightarrow x=-\dfrac{5}{18}\)
Vậy \(x=-\dfrac{5}{18}\)
\(\left(\dfrac{1}{4}-\dfrac{2}{3}\right):\dfrac{3x}{5}=\dfrac{5}{2}\Leftrightarrow\dfrac{-5}{12}:\dfrac{3x}{5}=\dfrac{5}{2}\Leftrightarrow\dfrac{3x}{5}=-\dfrac{1}{6}\Leftrightarrow x=-\dfrac{5}{18}\)
\(\left(\dfrac{1}{4}-\dfrac{2}{3}\right):\dfrac{3x}{5}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{-5}{12}:\dfrac{3x}{5}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{3x}{5}=\dfrac{-5}{12}:\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{3x}{5}=\dfrac{-1}{6}\)
\(\Leftrightarrow x=\dfrac{-1}{6}:\dfrac{3}{5}\)
\(\Leftrightarrow x=-\dfrac{5}{18}\)
Vậy \(x=-\dfrac{5}{18}\)
