If x≠1，is y equal to x+1?
(1)~$\frac{y-2}{x-1}$~=1
(2)y2=(x+1)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.
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
1: y-2=x-1 y=x+1
2: 这种情况y=x+1或y=-x-1.结果不唯一。
选A
（2）不是也可以推出结果嘛？是因为不是only解嘛？ 我以为只有问道具体的数值要求唯一解
