In this lesson, we will look into how to solve absolute value inequalities. Check out the lesson on what is meant by absolute value if necessary.

There are two types of absolute value inequalities, which are solved differently.

The “**less than**” type

For example:

The “**greater than**” Type

For example:

Let us first look at the “**less than**” type.

If the inequality looks like

then the solution looks like

–

c<x<c

**Example:**

Solve

** Solution: **

–5 < *x* < 5

** Example: **

Solve

** Solution: **

–4 < 2*x* – 3 < 4

To isolate x, first add 3 to each term of the inequality

–1 < 2*x* < 7

then divide each term by 2

Now, we will look at the “**greater than**” type

If the inequality looks like

then the solution looks like

x< –corx>c

**Example:**

Solve

** Solution: **

* x* < –5 or *x* > 5

** Example: **

Solve

** Solution: **

2*x* – 3 < –4 or 2*x* – 3 > 4

To isolate x, first add 3 to each term of the inequality

2*x* < –1 or 2*x* > 7

then divide each term by 2

Solve and graph the following inequality: |3x - 6| ≤ 12

Solve the absolute value inequality: |2x - 5| > 7
