The (unknown) x (I suppose that's what you mean) is a variable. It's commonly used to represent any number. For example if you have the equation 3x+2=5, x represents the number which will verify the equation. x can be used with equations, functions etc.

Well, Algebra usually goes through each lesson slower, and has less complicated problems to solve. Honors Algebra usually goes through each lesson faster and has more complicated problems to solve. Examples: Algebra--- x(6+1)=21 x=3 Honor's Algebra--- x(6*10)- -12+2=?

You use variables to stand for numbers in algebra
In algebra, x is the unknown for which you need the value.
In algebra we consider x,y and z are variables.
Variables stand in the place of unknown numbers. For example, in the following equation, one number is unknown: 2+x=5. The x takes the place of the number that is unknown.
Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
Sometimes... some variables can only stand for one thing, like m= slope, but "x" is a variable that can stand for just about anything; slope, axis, and equations.
