It is then possible to create a data table using the new equation.

Whichever pair of solutions makes the equation true is the correct answer. There are even word problems and an answer key included. Steps for Solving Linear Absolute Value Inequalities.

Then see how to solve for the answer write it in set builder notation and graph it on a number line. Notice that in the next two examples all the numbers outside of the absolute value are moved to one side first before the absolute value bars are removed and both positive and negative solutions are considered. That means you have the positive distance and the negative distance see below Or But when you divide multiply or divide by a negative number it flips the sign so you end up with Or Set up one inequality.
