The concept of equality: what we do to one side of the equation must be done to the other. http://t.co/RTExwarJEw via @khanacademy

To find the value of a variable you'll need to do something to BOTH sides of the equation. Watch. http://t.co/IINqZznBLN via @khanacademy

This equation can be simplified through a single step to solve for the variable. Can you help? http://t.co/QzUIMPI079 via @khanacademy

To achieve balance helps to explain why we do the same thing to both sides of an equation. http://t.co/E2Hy9Eh7UI via @khanacademy
