  1. \( 4 + 11 = 3x - 6 \)
  2. \( 55 = 12 x^2 - 53 \)
  3. \( 19x = 24x - 15 \)
  4. \( 6 = \frac{24}{x} \)
  5. \( 19 = \frac{31}{x} \)
  6. \( 36 = 16 + 2 \cdot 12 \left( x - 12 \right) \)
  7. \( 100 = 64 + 2 \cdot 10 \left( x - 30 \right) \)
  8. \( 81 = 25 + 2 \cdot \left( 18 - x \right) \)
  9. \( 64 = 16 + 2 \cdot \left( 20 - x \right) \)
  10. \( 100 = \frac{2 \cdot 4 \cdot 6}{x} \)
  11. \( 24 = 6 \sqrt{\frac{x}{3}} \)
  12. \( 40 = \frac{1}{4} \sqrt{\frac{x + 10}{3}} \)
  13. \( 50 = \frac{2}{3} \sqrt{\frac{x + 13}{0.4}} \)
  14. \( 500 = \frac{1}{2} \cdot 4 \cdot x^2 + 4 \cdot 10 \cdot 12 \)
  15. \( 200 = \frac{1}{2} \cdot x \cdot 5^2 + x \cdot 10 \cdot 14 \)
  16. \( 120 = \frac{3 \cdot 9 \cdot 12}{x^2} \)
  17. \( 300 = \frac{12 \cdot 3x}{9^2} \)
  18. \( 400 = \frac{3 \cdot 2 \cdot \left( 10 - 2 \right) }{x^2} \)
  19. \( \frac{1}{x} = \frac{1}{2} + \frac{1}{4} \)
  20. \( \frac{1}{10} = \frac{1}{x} + \frac{1}{20} \)
