x · \(1\,\frac{2}{23}\) − \(3\,\frac{2}{39}\) = \(1\,\frac{37}{39}\)
Переносим вычитаемое: x · \(\frac{25}{23}\) = \(1\,\frac{37}{39}\) + \(3\,\frac{2}{39}\) = \(\frac{76}{39}\) + \(\frac{119}{39}\) = \(\frac{195}{39}\) = 5. Тогда x = 5 : \(\frac{25}{23}\) = 5 · \(\frac{23}{25}\) = \(\frac{23}{5}\) = \(4\,\frac{3}{5}\). Проверка: (\(\frac{23}{5}\)) · (\(\frac{25}{23}\)) − \(\frac{119}{39}\) = 5 − \(3\,\frac{2}{39}\) = \(1\,\frac{37}{39}\). Ответ: \(4\,\frac{3}{5}\).
