Math Problem Statement
2∣x−7∣+3<17
Solution
We are given the inequality:
Step 1: Isolate the absolute value expression.
First, subtract 3 from both sides to get:
Next, divide both sides by 2:
Step 2: Break the absolute value into two inequalities.
For , we can rewrite it as a compound inequality:
Step 3: Solve the inequality.
Now, add 7 to all parts of the inequality:
Solution:
The solution to the inequality is:
This means that must be between 0 and 14 (but not including 0 or 14).
Would you like more details on any of the steps, or have any specific questions?
Here are 5 related questions to explore:
- What happens if the inequality were ?
- How would the solution change if the sign were instead of ?
- Can you graph the solution on a number line?
- How does the solution change if the absolute value is centered at a different point, e.g., ?
- What are the possible scenarios if the absolute value inequality includes a negative value?
Tip: Always start by isolating the absolute value expression when solving absolute value inequalities!
