What Is Variables In Math?

What is variable example?

In mathematics, a variable is a symbol or letter, such as “x” or “y,” that represents a value. For example, in the equation below, y is the “dependent variable ” because its value is based on the value assigned to the “independent variable ” x.

What is the variable in a math equation?

A symbol for a value we don’t know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable.

What are 3 types of variables?

There are three main variables: independent variable, dependent variable and controlled variables.

How do we solve for a variable?

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
