How to solve absolute value inequalities

How do you write an absolute value inequality? Chris Desiel. You can specify an absolute value by using a few vertical lines around that number. If you take the absolute value of a number, the result is always positive, even if the number itself is negative. The following two equations apply to the arbitrary number x: | x | = x y | x | = x.

What are the steps to solving equations and inequalities?

Solving Equations and Inequalities Add or subtract the x-term from both sides. If the coefficient of x is negative (term A), multiply all terms by 1. If there is a fraction, multiply all terms by the denominator to eliminate the fractions. If there is a decimal place, multiply all terms by a power of ten to eliminate the decimals.
