Solving Absolute Value Equations and Inequalities
Separate into four cases, since we don't know whether $ 3x-2$ and $ x+2$ are positive or negative. Since they are absolute values in the equations, they could be either, but still come out positive. For example, when the expression $ 3x-2$ is negative, the absolute value of that expression is the negation of it, or $ -3x+2$, to make it positive in the equation. Play around with some numbers ...

3.3: Absolute Value Inequalities
Solution. We begin the solution by rewriting the absolute value inequality using the cases in the definition. | 4x − 5 | ≥ 6 Case 2. Rewrite as two inequalities using or 4x − 5 ≥ 6 or 4x − 5 ≤ − 6 Solve each inequality 4x ≥ 11 or 4x ≤ − 1 Divide by the coefficient of x x ≥ 11 4 or x ≤ − 1 4 Solution in inequality notation.

We can solve radical equations by isolating the radical and raising both sides of the equation to a power that matches the index. 2.8: Linear Inequalities and Absolute Value Inequalities In this section, we will explore various ways to express different sets of numbers, inequalities, and absolute value inequalities.
2.5: Absolute Value Equations
The solution is the value (s) that are five units away from 0 on a number line. You might think of 5 right away; that is one solution to the equation. Notice that −5 − 5 is also a solution because −5 − 5 is 5 units away from 0 in the opposite direction. So, the solution to this equation |x|= 5 | x | = 5 is x =−5 x = − 5 or x= 5 x = 5.

Solving an Absolute Value Equation. Next, we will learn how to solve an absolute value equation. To solve an equation such as \(|2x−6|=8\), we notice that the absolute value will be equal to \(8\) if the quantity inside the absolute value bars is \(8\) or \(−8\). This leads to two different equations we can solve independently.
