Final answer:
To solve for x in the equation 9(x + 3) = 108, you need to distribute 9, simplify the equation, and isolate x. The steps in order are: rewrite the equation, distribute 9, and subtract 27.
Step-by-step explanation:
- Rewrite the equation as 9(x + 3) = 108.
- Distribute 9 to the terms inside the parentheses: 9x + 27 = 108.
- Subtract 27 from both sides of the equation: 9x = 81.
The correct steps in order to solve for x in the equation 9(x + 3) = 108 are: b) 9x + 27 = 108, d) 9x = 81, and a) x = 9.
