If x, y, and z are negative integers and 3x - 3y = -3z, then which of the following statements must be true?
I.	x > y>z
II.	x > y
III. x = z  Options:
A) I and II	B) I only	C) II only	D) III only	E) None
3x-3y=-3z   x-y=-z   Since z&lt;0; -z&gt;0   x-y&gt;0   x&gt;y   II correct.   We can't say much about z though;   x=-5; y=-100; z=-95   I and III incorrect.   Ans:II only
