Similar to an equation. The main difference is the following: when you multiply or divide by a negative number, you have to switch the sign. Example:

-3x < 12

Now divide by (-3):

x > -4

Note that, since I divided by a negative number, I had to change the "less than" to a "greater than". This rule becomes somewhat complicated when you need to multiply or divide by the variable - you have to consider different cases.
