Answer:
Here's how you can complete the proof:
Statement 1: 3x - 4 = 14 (Given)
Reason 1: Given
Statement 2: 3x - 4 + 4 = 14 + 4
Reason 2: Adding 4 to both sides of the equation
Statement 3: 3x = 18
Reason 3: Simplifying by adding 4 to both sides
Statement 4: x = 6
Reason 4: Dividing both sides by 3
So, the completed proof is as follows:
3x - 4 = 14 (Given)
3x - 4 + 4 = 14 + 4 (Adding 4 to both sides of the equation)
3x = 18 (Simplifying by adding 4 to both sides)
x = 6 (Dividing both sides by 3)
