Решение:
- 1. \[ 2x + 4 = 6x \]\[ 4 = 4x \]\[ x = 1 \]
- 2. \[ x = 2x - 3 \]\[ 3 = x \]
- 3. \[ 5 - x = 4x + 4 \]\[ 1 = 5x \]\[ x = \frac{1}{5} \]
- 4. \[ 3x - 4 = 5x + 2 \]\[ -6 = 2x \]\[ x = -3 \]
- 5. \[ 0 = 2x - 11 \]\[ 11 = 2x \]\[ x = \frac{11}{2} \]
- 6. \[ 9x + 4 = -5 \]\[ 9x = -9 \]\[ x = -1 \]
- 7. \[ -3x + 2 = 2x \]\[ 2 = 5x \]\[ x = \frac{2}{5} \]
- 8. \[ 11 + x = 2x \]\[ 11 = x \]
- 9. \[ 8x + 2 = 6x - 2 \]\[ 2x = -4 \]\[ x = -2 \]
- 10. \[ 3x = 2x + 4 \]\[ x = 4 \]
- 11. \[ 10x - 11 = 2 \]\[ 10x = 13 \]\[ x = \frac{13}{10} \]
