You are buying boxes of cookies at a bakery. Each box of cookies costs $4dollar sign, 4. In the graph below, c represents the number of boxes of cookies you buy, and d represents the amount the cookies will cost you (in dollars).

The relationship between these two variables can be expressed by the following equation:

d=4c

Suppose the boxes of cookies cost you $80

How many boxes of cookies did you buy?

To find how many boxes of cookies you bought by using the equation, you will try to isolate c. Therefore, you will replace d by $80 (80=4c).
So, to isolate C, you will need to divide both c and 80 by 4. 
80/4=20
4c/4=c
Therefore, you bought 20 boxes of cookies.
I hope this makes sense.
