Q22:
If –2x > 3y, is x negative?
(1) y > 0
(2) 2x + 5y – 20 = 0

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
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.

画直角坐标就会发现

2X+5y-20=0

-2X>3y

两者重迭区 x必小于0
