Math Problem Statement
Solution
The problem asks to solve the inequality algebraically. Let's go through the steps to solve it.
Step 1: Isolate the absolute value term
Start by adding 4 to both sides of the inequality to isolate the absolute value expression:
Step 2: Divide by 2
Next, divide both sides by 2:
Step 3: Remove the absolute value
To solve the inequality , consider the definition of absolute value. The inequality implies . Therefore:
Step 4: Solve the resulting compound inequality
Add 7 to each part of the inequality:
Final Answer:
The solution to the inequality is:
This means that can be any real number between and , but not including and .
