    1. Expand

    - 3 - 4m = 28m - 28 - 7m

    2. Simplify 28m - 28 - 7m to 21m - 28

    - 3 - 4m = 21m - 28

    3. Add 4m to both sides

    - 3 = 21m - 28 + 4m

    4. Simplify 21m - 28 + 4m to 25m - 28

    -3 = 25m - 28

    5. Add 28 to both sides

    - 3 + 28 = 25m

    6. Simplify - 3 + 28 to 25

    25 = 25m

    7. Divide both sides by 25

    1 = m

    8. Switch sides

    m = 1
