Step One:  The distributive property

4x = 7x - 21

Step Two: Subtraction of equals from both sides of the equation.

4x - 7x = 7x - 7x - 21  

Step Three

Collecting like terms

-3x = - 21

Step Four

Divide by - 3: division of equals.

-3x/-3 = -21/-3

x = 7

You have a list of these terms somewhere. Everyone writes these differently. You have to translate this into what your notes tell you they are.
