what is an equation

An equation is a mathematical statement that shows that two mathematical expressions are equal. It is a formula that expresses the equality of two expressions by connecting them with the equals sign = . For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math. Equations can be solved to find the value of an unknown variable representing an unknown quantity. In every equation in math, we have L.H.S = R.H.S (left-hand side = right-hand side) . Equations are used in algebra to describe geometric figures.
