Final answer:

A. x = (c - k) / 3. To solve for x in the equation 3x + k = c, subtract k from both sides of the equation and then divide both sides by 3.

Step-by-step explanation:

To solve for x in the equation 3x + k = c, we need to isolate x on one side of the equation. Here are the steps:

  1. Subtract k from both sides of the equation: 3x = c - k
  2. Divide both sides of the equation by 3: x = (c - k) / 3

Therefore, the correct answer is A. x = (c - k) / 3.
