Any letter in the alphabet can be used to represent a variable in algebra.
It is the multiplication operator. X is also probably the most commonly used letter for representing a variable in algebra and calculus. I was taught to always use a cursive x when representing a variable.
Why algebra has a different multiplication sign is because they don't want to mix up the American multiplication sign with the variable x. So they use a centered dot for algebra instead of this: x.
It is usually algebra whereas x is an unknown variable.
They are: x and y and the expression can be simplified to 6xy

A variable

In an equation the variable could be a letter!Like 2(x)+4=10 the variable is x! (:
It is called a variable. x is the most used variable.

In algebra, a variable is usually symbolized by the letter x. For more complex problems, the letters y and z are often used as well.

It depends what x is. If you do not know the value of either variable it would be 2x.
A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
Any variable can be declared as the independent variable, then the other would be the dependent variable. However, it is quite common to arbitrarily define y as the dependent variable - a variable that depends on x.
