B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

I'm going for C.

(1) x=11 or -17, hence insufficient
(2) restate as | x + 2 | = 13, therefore x=11 or -15 insufficient

(1) and (2) overlap on x=11, therefore sufficient. C.

Yes, you can, provided x >= 0. Otherwise, no.

Nihit, what is the source and what is the OE? Unless something is missing in the question (e.g. x is >=0, etc.), I do not see how D can be the answer.
