Final answer:

To solve for x in the equation QS = 3x + 3, subtract 3 from both sides and then divide by 3. The correct formula for x is (QS - 3)/3, which aligns with answer choice A.

Step-by-step explanation:

The question is asking to solve for x in the equation QS = 3x + 3. To find x, we need to isolate x on one side of the equation. Here's a step-by-step solution:

  1. Start with the given equation: QS = 3x + 3.
  2. Subtract 3 from both sides to get QS - 3 = 3x.
  3. Divide both sides by 3 to isolate x: (QS - 3)/3 = x.
  4. Therefore, x = (QS - 3)/3.

From the answer options given, the correct answer is A) x = (QS - 3)/3.
