A much easier way to approach this non-value DS question is to simply plug in integers and to seek both a Yes and No answer.
Also, even though you can simplify aka "translate" the stem, I don't recommend that you do so, as the original equation works fine, and you run the risk of human error. In the case of this question, it's actually condition #2 that benefits the most from a "translation."
1) Plug in x = 2 to get YES, and x = 4 to get NO. Not sufficient. Cross off A and D.
2) This condition is essentially telling us that x must be negative. Plug in any negative number (-1, -2, -3, etc.) and you will see that it works, and that the answer is always YES. Sufficient.
Hence, the correct answer is
Choice B.

Ever since graduating from Harvard with honors in the spring of 2002, I’ve worked as a private test-prep tutor, essay editor, author, and admissions consultant.
I’ve personally taken the GMAT 6 times, and have scored in the 700s each time, with personal bests of 770/800 composite, Quant 50/51, Verbal 48/51, IR 8 (2 times) and AWA 6 (4 times), with 3 consecutive 99% scores on Verbal. More importantly, however, I’ve coached hundreds of aspiring business school students to significantly better GMAT scores over the last two decades, including scores of as high as 720 (94%), 740 (97%), 760 (99%), 770, 780, and even the elusive perfect 800, with an average score improvement of over 120 points.
I've also scored a verified perfect 340 on the GRE, and a 179 (99%) on the LSAT.
