It depends on the font. Let's assume the simplest form of the letter X, which is just the diagonals of a perfect square.
In that case there are four: one vertical, one horizontal, and one along each of the diagonals.
There's also technically a fourfold axis of rotational symmetry perpendicular to the page.
It depends on how wide and how long the "x" is. Looking the way it does now, this "x" has two lines of symmetry.

Not many. Depending on how you write, the letters L, O, Q, and X can have diagonal lines of symmetry.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
Of the capital letters M, O, E, and X, -- M and E each have one line of symmetry, -- X has two lines of symmetry, or four if the cross lines were printed perpendicular, as they are in some fonts, -- O has an infinite number of lines of symmetry. My answer is justified by my firm conviction that it's correct.
the letter X has two lines of symmetry
If you mean the letter x, it has four lines of symmetry.
It has 2

How about: X
Lower case "o" and "x" both have two lines of symmetry. Upper case letters with two lines of symmetry are: "O," "X," "H" and "I."
