Задание 2. Решите уравнения: (3 балла)

Решение:

1. \( 2(7x + 11) - 5x = 5x \)
   \( 14x + 22 - 5x = 5x \)
   \( 9x + 22 = 5x \)
   \( 4x = -22 \)
   \( x = -\frac{22}{4} = -\frac{11}{2} = -5.5 \)
2. \( 2(4x - 5) - 14 - 3x = 6 \)
   \( 8x - 10 - 14 - 3x = 6 \)
   \( 5x - 24 = 6 \)
   \( 5x = 30 \)
   \( x = 6 \)
3. \( 13 - 6(3 - x) = 25 \)
   \( 13 - 18 + 6x = 25 \)
   \( -5 + 6x = 25 \)
   \( 6x = 30 \)
   \( x = 5 \)

Ответ: \( x = -5.5 \); \( x = 6 \); \( x = 5 \).
