In mathematics and science, equations are used to represent relationships between different quantities. These equations often contain variables, which are symbols that represent unknown values or quantities that can vary. Variables can be any letter, typically chosen from the alphabet, and they can represent different types of quantities such as numbers, measurements, or even physical properties. The purpose of using variables in equations is to express a general relationship rather than specific numerical values. By solving equations, we can determine the values or behaviors of these variables and gain a deeper understanding of the relationships they represent.
