Answer:

  m = 5

Step-by-step explanation:

Recognize that the number on the right has -3 as a factor. Divide both sides of the equation by -3.

  m -2 = 3

Add 2 to both sides of the equation:

  m = 5

_____

Additional comment

Perhaps the conventional approach is to eliminate parentheses, then solve the resulting 2-step linear equation.

  -3m +6 = -9

  -3m = -15 . . . . . . subtract 6 (step 1)

  m = 5 . . . . . . . . . divide by the coefficient of m (step 2)
