    To solve this problem, we should set up an equation, letting x be the unknown number.

    9 + x = 0

    Next, we should subtract 9 from both sides to cancel out the + 9 on the left side of the equation and get the variable alone.

    x = - 9.

    Therefore, the number you are looking for is - 9.
