Introduction
The difference between equation with variable on one side and equation with variables on two sides.
Pre-Requisites:
Basic knowledge about arithmetic operations and linear equations
Activity:
The distance is equal. One destination can be defined by a linear expression and the other by another expression. By equating these two expressions, we get the unit distance.
Real Life Question:
A purse contains 2-rupee and 5-rupee coins. The total sum of money is same when 2-rupee and 5-rupee coins are considered separately. The number of 2-rupee coins is 5/2 times 5-rupee coin. What is the total number of coins?

What you learn in Theory:
An Intro on how to solve equations with linear expressions on either sides.
What you learn in Practice:
It is known that by transposing the equation such that variables are brought to one side and the numbers to the other side. This has many applications in everyday situations as well as higher maths and applied science and commerce. This topic throws light on the importance of the concept.
