It doesn't always equal y or x. They're just convenient letters to use. You could use any letter or, for that matter, any symbol such as & or @.
Xouba (a sardine) and yogurt are foods that begin with the letters x and y.
In a problem where you are given two letters to add, subtract, multiply, divide, ect, you can put in any number you want for the letters. The only rule is that the two numbers must equal the number given. For Example: X=4 Y=5 X=3 Y=6 X=2 Y=7 X=1 Y=8 X=9 Y=0 X=10 Y=-1

The equation y x - x a is an algebraic equation that many learn in school, which involves numbers as well as letters. The equation y x - x a would be x (y-1).
The properties for real numbers are as follows:closure: for any numbers x and y, x + y is a real number.associativity: for any numbers x, y and z, x + (y + z) = (x + y) + z = x + y + zidentity: for any number x, there is a number, denoted by 0, such that x + 0 = x = 0 + xInvertibility: for any number x, there is a number denoted by -x such that x + (-x) = (-x) + x = 0Commutativity: for any numbers x and y, x + y = y + x.
The letters Q, U, X, Y, and Z
The answer to the equation y x - x a would be x(y-1). When letters are used in a math expression, this is a form of math called Pre-Algebra or Algebra.
Any letter can be used for math. The most common is x, y, z, a, b, & c.
The letters 'y', 'm', 'x' plus 'b' in mathematics mean a specific number in an algebraic equation. The objective is to work out what the values of the letters are.
