Final answer:
To solve the equation 7s = s - 8, subtract s from both sides of the equation to simplify it to 6s = -8. Divide both sides of the equation by 6 to solve for s, which gives s = -4/3.
Step-by-step explanation:
To solve the equation 7s = s - 8, we need to isolate the variable s on one side of the equation. We can start by subtracting s from both sides of the equation to get 7s - s = -8. Simplifying this gives us 6s = -8. Next, we divide both sides of the equation by 6 to solve for s. So, s = -8/6 = -4/3. Therefore, the correct answer is not given in the options provided.
