Question

The total of a number m and 12 is -18

Answer 1

answer:
`m = -1.2`

work:

`5m + 12 = -18` | subtract the 12 over to the -18, and solve.

`5m = -6` | divide by 5m on both sides, and solve.

`m = -1.2` | final answer.

Answer 2

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
