-when you multiply or divide by a negative you must flip the sign.
-when moving variables to the other side you move it by using the opposite operation.

Steps: Example: 2x+2>4x-4

1. Subtract 2 from positive 2 and negative 4, to give you 2x>4x-6.
2. Subtract 4x from 4x and 4x from 2x to give you -2x>-6.
3. Divide -2x by -2 and -6 by -2 to give you x>3.
4. You flip the sign whenever you divide or multiply by a negative number, therefore it turns into x<3.
