What is the value of |x| ?

(1) x = –|x|
x + |x| = 0 means that x could be 0 or x <0. INSUFFICIENT!

(2) x^2 = 4
\(\sqrt{x^2}=|x|=2\). SUFFICIENT!

We need to determine the value of |x|.

Statement One Alone:

x = -|x|

If x = -|x|, then x must be either zero or negative. However, we still do not have enough information to determine the value of |x|.

Statement Two Alone:

x^2 = 4

If x^2 = 4, then x is either 2 or -2.

If x = 2, then |x| = |2| = 2. If x = -2, then |x| = |-2| = 2. Either way |x| = 2.

Statement two alone is sufficient.

Answer: B
