x or any other variable
Unknonwn quantity is any variable a,b,c or x,y
define
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.
If we let the unknown number be represented by the variable x, then six more than the unknown number would be x + 6. This expression represents adding six to the unknown number. So, if you have an unknown number x, adding six to it gives you x + 6.
The unknown variable in that function.
v
In statistics, letter such as; a,..x..,z, is a variable used to represent an unknown value.
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
x or any other variable
X is the symbol for multiplication, as in 2X2=4 X (or any other letter) is often used to represent an unknown quantity.
They are used to represent known and unknown values in equations. Usually x, y, and z are unknown; and a, b, and c are known. But u can use anything to represent anything! It helps to solve for unknowns that you need to figure out!
A variable is assigned to represent an unknown quantity.

In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
Normally, alpha is used to represent an angle. Just like "x" is used to represent an unknown number or angle, alpha, theta, beta are used to represent unkown angles.
Let x represent the unknown number and use the known numbers to solve. Set up the equation: x + 9 = 15 (subtract 9 from each side to solve for the unknown number) x = 6
