What is an equation?

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic that have the same value.

The most basic and common algebraic equations in math consist of one or more variables.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign.

In an algebraic equation, the left-hand side is equal to the right-hand side.

Here, for example, 5x + 9 is the expression on the left-hand side, which is equal to the expression 24 on the right-hand side.
