  1. 1. \( -(a - b) = -a + b \)
  2. 2. \( (2a + 3c - 4b) = 2a + 3c - 4b \)
  3. 3. \( -(2 - a - 4n) = -2 + a + 4n \)
  4. 4. \( 2(3 + 2c) = 6 + 4c \)
  5. 5. \( -3(4c - 2a) = -12c + 6a \)
  6. 6. \( 5(4 - 2c) = 20 - 10c \)
  7. 7. \( -2(3 - 3n + 4m) = -6 + 6n - 8m \)
  8. 8. \( 4(a - 4c + 6d - n) = 4a - 16c + 24d - 4n \)
