For example : Soon or later, all of us use the service of a taxi driver

Taxi drivers usually charge a an initial fixed fee as part of using their services. Then, for each mileage, they charge a certain amount

Say for instance, the initial fee is 4 dollars and each mileage cost 2 dollars

The total cost can be modeled with an equation that is linear.

Let y be the total cost

Let N be number of mileage

Total cost = 4 + cost for N miles

Notice that cost for N miles = N×2

Therefore, y = 4 + N×2

Say for instance, a taxi driver takes you to a distance of 20 miles, how much money do you have to pay using y = 4 + N×2 ?

When N = 20, Y = 4 + 20×2 = 4 + 40 = 44 dollars

Now, let's ask the question the other way around!

If you pay 60 dollars, how far did the taxi driver took you?

This time y = 60

Replacing 60 into the equation gives you the following equation:

60 = 4 + N×2

It is not obvious to see that N = 28.
