Explanation:
Step 1: Define
Identify
2(x - 3) = (x - 1) + 7
Step 2: Solve for x
- Combine like terms [Addition]: 2(x - 3) = x + 6
- [Distributive Property] Distribute 2: 2x - 6 = x + 6
- [Addition Property of Equality] Add 6 on both sides: 2x = x + 12
- [Subtraction Property of Equality] Subtract x on both sides: x = 12
