What is the value of x ?
(1) x + 1 = 2 − 3x
(2) 1/(2x) = 2
(1) x + 1 = 2 − 3x
(2) 1/(2x) = 2
Statement One Alone:
x + 1 = 2 − 3x
Using the equation in statement one, we can determine a value for x.
x + 1 = 2 - 3x
4x = 1
x = ¼
Statement one is sufficient to answer the question. We can eliminate answer choices B, C, and E.
Statement Two Alone:
1/(2x) = 2
Using the equation in statement two, we can determine a value for x.
1/(2x) = 2
1 = 4x
x = ¼
Answer: D
