What_an_equation_is

The word 'equation' is derived from the word 'equal'. An Equation is a statement which defines the equality between variables and constants. The addition, subtraction, multiplication, and division of a number on both sides does not disturb this equality. Here we will learn various forms of equation like ax=b, a/x=b. We also learn methods to solve an equation.

Application_of_Simple_Equation_to_Practical_Situations

We can solve a variety of real world problems using simple equations. We start by forming an equation corresponding to the problem, the solution to this equation can then be found and applied in the real world!
