Решение:
Задание 1. Найдите корень уравнения:
- \[ x + 3 = -9x \]
- \[ 10x = -3 \]
- \[ x = -\frac{3}{10} \]
- \[ 6x + 1 = -4x \]
- \[ 10x = -1 \]
- \[ x = -\frac{1}{10} \]
- \[ -2x - 7 = -4x \]
- \[ 2x = 7 \]
- \[ x = \frac{7}{2} \]
- \[ -8x - 3 = -6x \]
- \[ -3 = 2x \]
- \[ x = -\frac{3}{2} \]
- \[ x - 2 = -3x \]
- \[ 4x = 2 \]
- \[ x = \frac{2}{4} = \frac{1}{2} \]
Ответ:
- 1) \[ x = -\frac{3}{10} \]
- 2) \[ x = -\frac{1}{10} \]
- 3) \[ x = \frac{7}{2} \]
- 4) \[ x = -\frac{3}{2} \]
- 5) \[ x = \frac{1}{2} \]
