Answer:

x = (-d - b)/(d - 9)

Step-by-step explanation:

Step 1: Write equation

dx + b = 9(x - d)

Step 2: Solve for x

  1. Distribute 9: dx + b = 9x - 9d
  2. Subtract 9x on both sides: dx - 9x + b = -d
  3. Subtract b on both sides: dx - 9x = -d - b
  4. Factor out x: x(d - 9) = -d - b
  5. Divide both sides by d - 9: x = (-d - b)/(d - 9)
