Well then you need to use inverse operations. SO......

Since it is addition you do subtraction.

-18 - 12

-18 + -12

-30      SOOOOO.......

-30 + 12 = -18

-18 = -18

M = -30

answer:  [tex]m = -1.2[/tex]

work:

[tex]5m + 12 = -18[/tex]  | subtract the 12 over to the -18, and solve.

[tex]5m = -6 [/tex]  | divide by 5m on both sides, and solve.

[tex]m = -1.2[/tex]  | final answer.

hope this helps! ❤ from peachimin
