7. Решите уравнение: 1) \frac{4}{7}b + \frac{3}{7}b + 2 = 14 2) \frac{2}{3}a + \frac{10}{12}a - \frac{3}{6}a = 24 3) 4\frac{1}{10}x - 3\frac{5}{15}x = \frac{23}{30}

7. Решите уравнение:

1. \(\frac{4}{7}b + \frac{3}{7}b + 2 = 14\)
   \(\frac{7}{7}b = 12\)
   \(b = 12\)
2. \(\frac{2}{3}a + \frac{10}{12}a - \frac{3}{6}a = 24\)
   \(\frac{8}{12}a + \frac{10}{12}a - \frac{6}{12}a = 24\)
   \(\frac{12}{12}a = 24\)
   \(a = 24\)
3. \(4\frac{1}{10}x - 3\frac{5}{15}x = \frac{23}{30}\)
   \(4\frac{1}{10}x - 3\frac{1}{3}x = \frac{23}{30}\)
   \(\frac{41}{10}x - \frac{10}{3}x = \frac{23}{30}\)
   \(\frac{123}{30}x - \frac{100}{30}x = \frac{23}{30}\)
   \(\frac{23}{30}x = \frac{23}{30}\)
   \(x = 1\)

Ответ: 1) \(b=12\), 2) \(a=24\), 3) \(x=1\)
