Final answer:
To prove x = 3 given 2x - 4 = 2, add 4 to both sides, simplify the equation, divide by 2, and simplify again to get x = 3.
Step-by-step explanation:
To prove: x = 3
Given: 2x - 4 = 2
Steps:
- Add 4 to both sides of the equation: 2x - 4 + 4 = 2 + 4
- Simplify the equation by combining like terms: 2x = 6
- Divide both sides of the equation by 2 to solve for x: 2x/2 = 6/2
- Simplify the equation to get the final answer: x = 3
