What is the value of x?
(1) 3x – 1 = x
(2) 1/x + 1 = 3
(1) 3x – 1 = x
(2) 1/x + 1 = 3
Target question: What is the value of x?
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
