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
