Answer: 5
Explanation:
1. Distribute 4(c-3), and that will be 4c - 12 = 8
2. Add 12 to 12 and 8 and then cancel out the 12 because it will be 0 so we dont need that anymore
3. So that leaves us with 4c = 8 + 12
4. Add 8+ 12 and that will give us 20
5. Divided 20 and 4 and the answer will be 5
More simple explanation
1. 4(c-3)=8
2. 4c-12=18
3. 4c-12+12=18+12
4. 4c=18+12
5. 4c=20
6. 5
