б) x - \(\frac{2}{3}\) = \(\frac{2}{4}\);

б) x - \(\frac{2}{3}\) = \(\frac{2}{4}\)

x = \(\frac{2}{4}\) + \(\frac{2}{3}\)

x = \(\frac{2 \cdot 3}{4 \cdot 3}\) + \(\frac{2 \cdot 4}{3 \cdot 4}\)

x = \(\frac{6}{12}\) + \(\frac{8}{12}\)

x = \(\frac{6 + 8}{12}\)

x = \(\frac{14}{12}\) = \(\frac{7}{6}\) = 1 \(\frac{1}{6}\)

Ответ: 1 \(\frac{1}{6}\)
