Understanding Absolute Value Inequalities
Absolute value inequalities are mathematical expressions that involve the absolute value of a variable and an inequality sign. The absolute value of a number is its distance from zero on the number line, which means it is always non-negative. For example, the absolute value of -3 and 3 is both 3.
When dealing with inequalities, absolute value can create two distinct scenarios:
1. Positive Case: The expression inside the absolute value is greater than or equal to zero.
2. Negative Case: The expression inside the absolute value is less than zero.
This leads to two separate inequalities that must be solved individually. Absolute value inequalities can be expressed in two forms:
- Less Than (<) or Less Than or Equal To (≤): This indicates that the expression lies within a certain distance from a point.
- Greater Than (>) or Greater Than or Equal To (≥): This indicates that the expression lies outside a certain distance from a point.
Types of Absolute Value Inequalities
There are two primary types of absolute value inequalities:
1. Compound Inequalities: These inequalities involve two parts where the absolute value expression is less than a certain value. For example:
\[
|x - 3| < 5
\]
This implies:
\[
-5 < x - 3 < 5
\]
2. Split Inequalities: These inequalities involve the absolute value being greater than a certain value. For example:
\[
|x + 2| > 4
\]
This leads to two separate inequalities:
\[
x + 2 > 4 \quad \text{or} \quad x + 2 < -4
\]

How to Solve Absolute Value Inequalities
Solving absolute value inequalities involves a systematic approach. Here’s a step-by-step guide:
1. Isolate the Absolute Value: Ensure that the absolute value expression is on one side of the inequality.
Example:
\[
|3x + 1| < 7
\]
2. Set Up Two Cases: Depending on whether the inequality is less than or greater than, set up the corresponding cases.
For less than:
\[
-7 < 3x + 1 < 7
\]
For greater than:
\[
3x + 1 > 7 \quad \text{or} \quad 3x + 1 < -7
\]
3. Solve Each Case: Solve the resulting inequalities for each case.
- For \(3x + 1 < 7\):
\[
3x < 6 \implies x < 2
\]
- For \(3x + 1 > -7\):
\[
3x > -8 \implies x > -\frac{8}{3}
\]
4. Combine Solutions: Depending on the type of inequality, combine the solutions appropriately.
- For less than:
\[
-\frac{8}{3} < x < 2
\]
- For greater than, combine as:
\[
x > 6 \quad \text{or} \quad x < -8
\]
