Expanding the left side of the equation:

-4(5) - 4(2m) + 3m - 12 = 6(2) - 6(-m) - 5m
-20 - 8m + 3m - 12 = 12 + 6m - 5m

Combining like terms:

-20 - 5m - 12 = 12 + m
-5m - 32 = 12 + m

Adding 5m to both sides:

-32 = 12 + 6m

Subtracting 12 from both sides:

-44 = 6m

Dividing by 6:

m = -44/6
m = -22/3

Therefore, the solution to the equation is m = -22/3.
