Web3 jul. 2024 · So, x ≠ 2, which means it must be the case that x = 4. Since we can answer the target question with certainty, statement 1 is SUFFICIENT. Statement 2: x = 2 x − 2. Once again, we'll test the two possible x-values. Test x = 2, to get: 2 = 2 2 − 2, which we can simplify to get: 2 = 1.
