Target question: What is the value of x ?
Statement 1: x + 1 = 2 - 3x
At 3x to both sides of the equation to get: 4x + 1 = 2
Subtract 1 from both sides: 4x = 1
Solve:
x = 0.25
Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: 1/(2x) = 2
Multiply both sides of the equation by 2x to get: 1 = 4x
Solve:
x = 0.25
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
