Explanation:
Step 1: Define
Identify
4(1) + 12(x + 3) - 6(x - 5) = 4(12) + 4(x)
Step 2: Solve for x
- Simplify: 4 + 12(x + 3) - 6(x - 5) = 48 + 4x
- [Distributive Property] Distribute parenthesis: 4 + 12x + 36 - 6x + 30 = 48 + 4x
- Combine like terms: 6x + 70 = 48 + 4x
- [Subtraction Property of Equality] Subtract 4x on both sides: 2x + 70 = 48
- [Subtraction Property of Equality] Subtract 70 on both sides: 2x = -22
- [Division Property of Equality] Divide 2 on both sides: x = -11
