Math Problem Statement

2∣x−7∣+3<17

Solution

We are given the inequality:

2x7+3<172 |x - 7| + 3 < 17

Step 1: Isolate the absolute value expression.

First, subtract 3 from both sides to get:

2x7<142 |x - 7| < 14

Next, divide both sides by 2:

x7<7|x - 7| < 7

Step 2: Break the absolute value into two inequalities.

For x7<7|x - 7| < 7, we can rewrite it as a compound inequality:

7<x7<7-7 < x - 7 < 7

Step 3: Solve the inequality.

Now, add 7 to all parts of the inequality:

0<x<140 < x < 14

Solution:

The solution to the inequality is:

0<x<140 < x < 14

This means that xx 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:

  1. What happens if the inequality were 2x7+3172 |x - 7| + 3 \geq 17?
  2. How would the solution change if the sign were \leq instead of <<?
  3. Can you graph the solution on a number line?
  4. How does the solution change if the absolute value is centered at a different point, e.g., x5|x - 5|?
  5. 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!
