X + Y equals the sum of X and Y.

Letters such as X and Y are "unknown quanitites", meaning they stand in for unknown numbers in an equation.
For example, 2X = 10 means "2 times what equals 10".
The only problem is when you have an equation like X+Y=10, the X could be any number and the Y could be any number where the 2 added together is the answer (10 in this example).
- X could be 9 and Y would be 1
- X could be 8 and Y would be 2
etc.

X+Y = X+Y. Unless you can give values for X and Y, that's as far as you can take it.
"X" and "Y" are also often used as the two axes (plural of "axis") of a cartesian coordinate system, used for graphing or plotting points. However, an incomplete expression like "X+Y" is meaningless in this context. If X and Y were the coordinates of a point, you'd write it as (X,Y).

? is literally what you get when you take one numeric value called X and use the aritmetic operation called addition to put that value together with another numeric value called Y.
The literal, logical exposition of this can be deduced from the findings in volume 3 of Principia Mathematica by Whitehead and Russell.

X and Y are actually algebraic variables whose value is unknown.
X and Y could any number. The above expression is the sum of two variables whose value is not known.

i dont know if i got it...
x and y are universally used in math equations. Geometry uses it too to represent the axles (which can also relate to equations)
