Question

Solve the equation for x
dx + b = 9(x - d)

Answer 1

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

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)
