    You subtract 9 from both sides

    Step-by-step explanation:

    You have to get the variable by itself to solve so you subract 9 by 9 and they cancel each other out. Then you do - 12-9 and since they are both negative you get get - 21

    Them you have your answer m=-21, you can check this by plugging m inot the equation

    m + 9 = - 12

    - 9 - 9

    M = - 21
