Whatever you want it to be. In mathematics, letters are used for "variables", placeholders for a number which is not specified. Sometimes you are supposed to find a value of "y" so that a certain equation is true. For example, if y + 5 = 8, the only correct value for y is 3. In another equation, "y" may have a different value.
