Решение:
\(\frac{1}{3}\)y - (2y - \(\frac{2}{3}\)) + 5 = \(\frac{1}{3}\)y - 2y + \(\frac{2}{3}\) + 5 = (\(\frac{1}{3}\) - 2)y + (\(\frac{2}{3}\) + 5) = (\(\frac{1}{3}\) - \(\frac{6}{3}\))y + (\(\frac{2}{3}\) + \(\frac{15}{3}\)) = -\(\frac{5}{3}\)y + \(\frac{17}{3}\) = -1\(\frac{2}{3}\)y + 5\(\frac{2}{3}\)
Ответ: -1\(\frac{2}{3}\)y + 5\(\frac{2}{3}\)
