\(\dfrac{2}{3}x-\dfrac{1}{4}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{2}{3}x=\dfrac{11}{4}\)
\(\Rightarrow x=\dfrac{33}{8}\)
\(\dfrac{2}{3}x-\dfrac{1}{4}=\dfrac{5}{2}\)
\(\Leftrightarrow\dfrac{2}{3}x=\dfrac{5}{2}+\dfrac{1}{4}\)
\(\Leftrightarrow\dfrac{2}{3}x=\dfrac{11}{4}\)
\(\Leftrightarrow x=\dfrac{33}{8}\)
Vậy \(x=\dfrac{33}{8}\)
\(\dfrac{2}{3x}-\dfrac{1}{4}=\dfrac{5}{2}\) đk (x khác 0)
=>8-3x=30x
=>8=33x
=>x=8/33
\(\dfrac{2}{3}x-\dfrac{1}{4}=\dfrac{5}{2}\)
\(\dfrac{2}{3}x=\dfrac{5}{2}+\dfrac{1}{4}\)
\(\dfrac{2}{3}x=\dfrac{11}{4}\)
\(x=\frac{11}{4}:\frac{2}{3} \)
\(x=\frac{33}{8} \)
\(\dfrac{2}{3}x-\dfrac{1}{4}=\dfrac{5}{2}\)
\(\dfrac{2}{3}x=\dfrac{5}{2}+\dfrac{1}{4}\)
\(\dfrac{2}{3}x=\dfrac{11}{4}\)
\(x=\dfrac{11}{4}:\dfrac{2}{3}\)
\(x=\dfrac{33}{8}\)
