What is the value of x ?
(1) x + 1 = 2 - 3x
(2)~$1 \over 2x$~ =2
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析：
（1）x + 1 = 2 − 3x解得x=~$\frac{1}{4}$~，题目得解。
（2）~$\frac{1}{2x}=2$~，解得x=~$\frac{1}{4}$~，题目得解。
因此，本题答案为（D），任何一个条件说明均能解题。
