Hello Phoebe,

Variables are used as placeholders for numbers that are the answers to 
questions or solutions to problems. For example:

   X + 6 = 14

What is the number that you can add to 6 to get a sum of 14? In order 
to find that number, you have to solve for X. Using variables helps us 
to find the numbers that fit a given equation, or answer a certain 
question, but they do not take the place of numbers. 

Please write in again if you have more questions.
