What are the steps to find the solution to an inequality?

kifflom [539]

Answer:

Very similar to solving an equation.

Step-by-step explanation:

You have to use the properties of equality to "undo" each number and isolate the letter to one side.

How ever, if you are multiplying or dividing by a negative number, then the inequality must be reversed.
