Ответ:

Решение:

  1. \( 1 - 10x - 2 = 15 \Rightarrow -10x = 16 \Rightarrow x = -1.6 \)
  2. \( 8 - 48 - 18x = 13 \Rightarrow -18x = 53 \Rightarrow x = -\frac{53}{18} \)
  3. \( 2 - 21 - 6x = 11 \Rightarrow -6x = 20 \Rightarrow x = -\frac{10}{3} \)
  4. \( 2 - 6 - 9x = 14 \Rightarrow -9x = 16 \Rightarrow x = -\frac{16}{9} \)
  5. \( x - 6x - 4 = 16 \Rightarrow -5x = 20 \Rightarrow x = -4 \)
  6. \( 3x - 6x - 8 = 10 \Rightarrow -3x = 18 \Rightarrow x = -6 \)
  7. \( -4x = 15 - 9x + 15 \Rightarrow 5x = 30 \Rightarrow x = 6 \)
  8. \( 1 - 7x = 13 - 16x + 14 \Rightarrow 9x = 26 \Rightarrow x = \frac{26}{9} \)
  9. \( 1 - 5x = 11 - 8x + 4 \Rightarrow 3x = 14 \Rightarrow x = \frac{14}{3} \)
  10. \( 7 - 15x + 9 = -11 \Rightarrow -15x = -27 \Rightarrow x = \frac{9}{5} \)
  11. \( 7x - 15 = 4x - 3x + 9 \Rightarrow 6x = 24 \Rightarrow x = 4 \)
  12. \( 4x - 6 - 9x + 4 = 18 \Rightarrow -5x = 20 \Rightarrow x = -4 \)
  13. \( 15x + 24 - 7x = 6x \Rightarrow 2x = -24 \Rightarrow x = -12 \)
  14. \( 5x - 22 = 9x \Rightarrow -4x = 22 \Rightarrow x = -5.5 \)
  15. \( 5x - 18 = 9x \Rightarrow -4x = 18 \Rightarrow x = -4.5 \)
  16. \( 16 + 6x = 5 - 10x \Rightarrow 16x = -11 \Rightarrow x = -\frac{11}{16} \)

Ответ: 1) \( x = -1.6 \) 2) \( x = -\frac{53}{18} \) 3) \( x = -\frac{10}{3} \) 4) \( x = -\frac{16}{9} \) 5) \( x = -4 \) 6) \( x = -6 \) 7) \( x = 6 \) 8) \( x = \frac{26}{9} \) 9) \( x = \frac{14}{3} \) 10) \( x = \frac{9}{5} \) 11) \( x = 4 \) 12) \( x = -4 \) 13) \( x = -12 \) 14) \( x = -5.5 \) 15) \( x = -4.5 \) 16) \( x = -\frac{11}{16} \)
