Math Problem Statement
|x + 2| > 9
Solution
The inequality shown in the image is:
To solve this absolute value inequality, we break it into two cases based on the definition of absolute value:
Case 1:
Solve :
Case 2:
Solve :
Thus, the solution to the inequality is:
This means must be either greater than 7 or less than -11.
