## Definition Of Simple Equations

A simple equation is a relationship of two different mathematical expressions on either side of an ‘equal to (=)’ sign. It is expressed in a simple linear equation for instance, 2x – 4 = 2.

Here, x is a variable. The purpose of this chapter is to help students learn how to find the value of x.

## Important Points To Know To Solve Simple Equations

Every chapter has a variety of questions but to solve all of them there are some set of rules. Knowing such rules or important points at this time is important for you.

Depending upon the equations it can have one or two variables but the simplest way to solve it is by balancing the equation and reordering the numbers.

While reordering the numbers the signs of the number change for example, If a number is positive before the sign and you reorder them to write the same number on the other side of equal sign, then it will become a negative number.

While balancing the equation, the number on both sides of equal should be the same.

The application of simple equations are used in our everyday life such as in traffic control, aircraft, space programs and more.
