\(x\) \(\times\) 5 + \(x\) : 5 = \(x\) + \(\dfrac{3}{5}\)
\(x\) \(\times\) 5 + \(x\) \(\times\) \(\dfrac{1}{5}\) = \(x\) + \(\dfrac{3}{5}\)
\(x\) \(\times\) (5 + \(\dfrac{1}{5}\)) = \(x\) + \(\dfrac{3}{5}\)
\(x\) \(\times\) \(\dfrac{26}{5}\) = \(x\) + \(\dfrac{3}{5}\)
\(x\times\) \(\dfrac{26}{5}\) - \(x\) = \(\dfrac{3}{5}\)
\(x\) \(\times\) \(\dfrac{26}{5}\) - \(x\times\) 1 = \(\dfrac{3}{5}\)
\(x\) \(\times\) ( \(\dfrac{26}{5}\) - 1) = \(\dfrac{3}{5}\)
\(x\) \(\times\) \(\dfrac{21}{5}\) = \(\dfrac{3}{5}\)
\(x\) = \(\dfrac{3}{5}\) : \(\dfrac{21}{5}\)
\(x\) = \(\dfrac{1}{7}\)
