We have the following equation:

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

-3m + 4 + 4m = -1

Like terms:

-3m + 4m = -1 - 4

m = -5

Let's prove our answer replacing m by -5 on the original equation , this way:

-3 * - 5 + 2 (2 + 2 * -5) = -1

15 + 2 (2 -10) = -1

15 + 2 * -8 = -1

15 - 16 = -1

-1 = -1

Our answer is correct
