Step-by-step explanation:

Step 1: Define

9m - m + 3 = -2(m + 1)

Step 2: Solve for m

Combine like terms:                    8m + 3 = -2(m + 1)Distribute -2:                                8m + 3 = -2m - 2Add 2m on both sides:                10m + 3 = -2Isolate m term:                             10m = -5Isolate m:                                      m = -1/2
