A letter used to represent an unknown number is called a "variable." In mathematics, variables are often denoted by letters such as x, y, or z. They are used in equations and expressions to stand in for values that can change or are not yet known. Variables play a crucial role in algebra and various branches of mathematics.
X and y
That means that the two expressions represent the same number.
A letter or symbol that stands for a number or numbers is called a "variable." In mathematics, variables are used to represent unknown values and can take on different values in equations or expressions. Commonly used variables include letters such as x, y, and z. They play a crucial role in algebra and other branches of mathematics.
Yes, a letter can serve as a coefficient in algebraic expressions. In this context, the letter represents a constant value that multiplies a variable. For example, in the expression (3x), the number 3 is a coefficient, while in an expression like (kx), (k) is a letter that acts as a coefficient. This usage allows for more general expressions in mathematical equations.
It represents a number that is unknown in a problem. For example,16 + x = 44.In this case "x" would represent the number 28 in the problem.

No single number can be negative or positive. There are equations or expressions whose value can be either but not a number.

In math, the letter "n" is commonly used as a variable to represent a number that is not specified. It is often used in equations and formulas to indicate a variable quantity that can take on different values.
The letter that represent the composite number is letter C.
It means that two expressions represent the same number.
x may not always represent a positive number because there are equations that make a variable a negative number
