    The correct answer is A. The addition property of equality was not applied correctly.

    Explanation:

    The addition property of equality essentially states that whatever you add to one side of the equation, you must add the same amount to the other side. In this case, the person who done the work should've added - 8 to both sides, but ended up adding - 8 to one side and 8 to the other side, which aren't the same quantity.
