Final answer:

To solve the equation 2x - 43 = 2 and prove that x = 5, we will follow these steps: Add 43 to both sides of the equation, simplify, divide by 2, simplify further. Therefore, the solution to the equation is x = 22.5, not x = 5.

Step-by-step explanation:

To solve the equation 2x - 43 = 2 and prove that x = 5, we will follow these steps:

  1. Add 43 to both sides of the equation: 2x - 43 + 43 = 2 + 43
  2. Simplify: 2x = 45
  3. Divide both sides of the equation by 2: 2x / 2 = 45 / 2
  4. Simplify: x = 22.5

Therefore, the solution to the equation 2x - 43 = 2 is x = 22.5, not x = 5. The given statement is incorrect.
