Variables in equations are a part of many important math topics. We can define an equation as a mathematical statement which is composed of two expressions which are connected by an equal sign. There are various types of equations, namely, linear equations, quadratic equations, cubic equations, and so on. We take the help of graphs to plot points of the equations to understand it more vividly. Variables in an equation can take up different numericals values.
