3(m + 4) - 2(2m + 3) = - 4

Sure, let's solve the equation step by step:

1. Distribute the numbers outside the parentheses to the terms inside the parentheses:

   3m + 12 - 4m - 6 = -4

2. Combine like terms:

   -m + 6 = -4

3. Subtract 6 from both sides to isolate the variable term:

   -m = -4 - 6

4. Simplify the right side:

   -m = -10

5. Multiply both sides by -1 to solve for m:

   m = 10
