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.

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
2 lines of symetry

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."
