Question

M + 9 = -12 what do you do first

Answer 1

Answer:

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

Answer 2

If you are solving for M

You would subtract 9

m + 9 = -12

    - 9    - 9

M = -21
