X is the most famous variable in algebra, and a variable is a letter that stands for a number. It is used for you to apply methods of problem solving to get the answer, and the answer will be what x stands for. For example, if you see the problem 48-2x=100, you know you have to solve for x. The next step would be to subtract 48 from both ends of the equation, so you get (48-2x) -48= (100) -48 ---> -2x=52. Then you divide each side by -2 to get x by itself ---> -2x/2=52/-2 ---> x= -26. So you can see that x is not one specific number, it is just a variable.
In algebra we consider x,y and z are variables.
Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
() x=y(x)xy(x)(x)=() (). X=
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.
X/4
In algebra, x is the unknown for which you need the value.

x2
Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
x+7
x is the unknown number in algebra
Oh honey, algebra is just a fancy way of saying we're gonna add some letters together. So, if you wanna know what x plus y is, well, it's just x plus y. No magic tricks here, just basic math. Hope that clears things up for ya!
