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