Statement 1: 3x – 1 = x Subtract x from both sides: 2x  1 = 0 Add 1 to both sides: 2x = 1 Solve: x = 1/2 Since we can answer the target question with certainty, statement 1 is SUFFICIENT Statement 2: 1/x + 1 = 3 Subtract 1 from both sides: 1/x = 2 Multiply both sides by x to get: 1 = 2x Solve: x = 1/2 Since we can answer the target question with certainty, statement 2 is SUFFICIENT Answer: D
