Math Problem Statement
|x|>−1
Solution
To solve the inequality , we need to consider the properties of absolute values and inequalities.
Step 1: Understand the inequality
The absolute value represents the distance of from 0 on the number line. By definition:
This means that is always non-negative. The smallest value can take is 0 (when ).
Step 2: Analyze the inequality
The inequality is . Since is always non-negative and is negative, will always be greater than for any real number .
Conclusion:
Since is always greater than for any real number , the solution is:
This means every real number satisfies the inequality .

- How would the solution change if the inequality were instead of ?
- What are the implications if the inequality was instead?
- How would the solution change if the inequality were ?
- What is the effect of changing the sign inside the absolute value, such as ?
Tip: Remember that the absolute value of any real number is always non-negative, so inequalities involving absolute values often have different properties from regular linear inequalities.
