Ответ:

Решение:

  1. \( 4x - 3 = 0 \)

  2. \( 4x = 3 \)
    \( x = \frac{3}{4} \)
  3. \( 5x + 6 = 0 \)

  4. \( 5x = -6 \)
    \( x = -\frac{6}{5} \)
  5. \( -5x - 24 = 0 \)

  6. \( -5x = 24 \)
    \( x = -\frac{24}{5} \)
  7. \( -12x + 45 = 0 \)

  8. \( -12x = -45 \)
    \( x = \frac{-45}{-12} = \frac{15}{4} \)

Ответ: a) \( x = \frac{3}{4} \); б) \( x = -\frac{6}{5} \); в) \( x = -\frac{24}{5} \); г) \( x = \frac{15}{4} \).
