Do you place a or an in front of x?

Question

example: sign your name where I placed (an or a) x

Answer 1

I would say: an x. Why? I know x is not a vowel, the usual requirement, but phonetically x is pronounced with an e like ex, and therefore it sounds better to me to say "an" x.

Answer 2

an for sure, a x just sounds wrong.

Answer 3

An

Answer 4

If x takes the sound of ex as in x-ray, than you use an; if x takes the sound of z as in xylophone you use a.
