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
