What are Equations?
To put it simply, an equation is a statement in mathematics that says that two things are equal. It has an equals sign "=" like this: 2 + 3 = 5. In algebra, the definition of an equation is 'a mathematical statement that consists of an equal symbol between two algebraic expressions that have the same value.' In math, the most common and basic algebraic equations, there are one or more variables. Let's look at an example: 4x + 10 = 20 is an equation in which 4x + 10 and 20 are two expressions separated by an 'equal' sign. In an algebraic expression, the right-hand side is equal to the left-hand side. Here, for example, 4x + 10 is the expression on the left-hand side, which is equal to the expression 20 on the right-hand side. The process of finding the value of the variable is called solving the equation.
