x + 42 = 7 11 38+ a = 61 9 9-y=70 5 b-3 = 116 17 17+ z-44 = 25 7 7 0513c=311 13

1) x + 4\(\frac{2}{11}\) = 7

• Выразим x:
• \(x = 7 - 4\frac{2}{11}\)
• \(x = 7 - \frac{46}{11}\)
• \(x = \frac{77}{11} - \frac{46}{11}\)
• \(x = \frac{31}{11}\)
• \(x = 2\frac{9}{11}\)

Ответ: \(x = 2\frac{9}{11}\)

2) 9\(\frac{1}{5}\) - y = 7\(\frac{3}{5}\)

• Выразим y:
• \(y = 9\frac{1}{5} - 7\frac{3}{5}\)
• \(y = \frac{46}{5} - \frac{38}{5}\)
• \(y = \frac{8}{5}\)
• \(y = 1\frac{3}{5}\)

Ответ: \(y = 1\frac{3}{5}\)

3) z - 4\(\frac{4}{7}\) = 2\(\frac{5}{7}\)

• Выразим z:
• \(z = 2\frac{5}{7} + 4\frac{4}{7}\)
• \(z = \frac{19}{7} + \frac{32}{7}\)
• \(z = \frac{51}{7}\)
• \(z = 7\frac{2}{7}\)

Ответ: \(z = 7\frac{2}{7}\)

4) 3\(\frac{8}{9}\) + a = 6\(\frac{1}{9}\)

• Выразим а:
• \(a = 6\frac{1}{9} - 3\frac{8}{9}\)
• \(a = \frac{55}{9} - \frac{35}{9}\)
• \(a = \frac{20}{9}\)
• \(a = 2\frac{2}{9}\)

Ответ: \(a = 2\frac{2}{9}\)

5) b - \(\frac{3}{17}\) = 1\(\frac{16}{17}\)

• Выразим b:
• \(b = 1\frac{16}{17} + \frac{3}{17}\)
• \(b = \frac{33}{17} + \frac{3}{17}\)
• \(b = \frac{36}{17}\)
• \(b = 2\frac{2}{17}\)

Ответ: \(b = 2\frac{2}{17}\)

6) 5\(\frac{6}{13}\) - c = 3\(\frac{11}{13}\)

• Выразим c:
• \(c = 5\frac{6}{13} - 3\frac{11}{13}\)
• \(c = \frac{71}{13} - \frac{50}{13}\)
• \(c = \frac{21}{13}\)
• \(c = 1\frac{8}{13}\)

Ответ: \(c = 1\frac{8}{13}\)
