What makes an expression or an equation algebraic?

An algebraic is a mathematical phrase where two sides of the phrase are connected by an equal sign (=). For example, 3x + 5 = 20 is an algebraic equation where 20 represents the right-hand side (RHS), and 3x +5 represents the left-hand side (LHS) of the equation.

What is an example of a equation?

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign.
