Math Problem Statement

Solve the inequality involving absolute value: |(x - 3)/6| < 4.

Solution

To solve the inequality x36<4\frac{|x - 3|}{6} < 4, we can break down the process as follows:

Step 1: Remove the Fraction

First, eliminate the fraction by multiplying both sides by 6: x3<24|x - 3| < 24

Step 2: Solve the Absolute Value Inequality

The inequality x3<24|x - 3| < 24 means that the distance between xx and 3 is less than 24. This can be rewritten as a compound inequality: 24<x3<24-24 < x - 3 < 24

Step 3: Solve for xx

Add 3 to each part of the inequality to isolate xx: 24+3<x<24+3-24 + 3 < x < 24 + 3 21<x<27-21 < x < 27

Step 4: Write the Solution in Interval Notation

The solution in interval notation is: (21,27)(-21, 27)

Thus, the solution to the inequality is: (21,27)(-21, 27)

Here are some related questions to expand on this topic:

  1. How do you solve absolute value inequalities of the form ax+b>c|ax + b| > c?
  2. How would the solution change if the inequality was x364\frac{|x - 3|}{6} \leq 4?
  3. What happens if there is a negative coefficient inside the absolute value, like x+3<4|-x + 3| < 4?
  4. How do you graph the solution of an absolute value inequality on a number line?
  5. What is the difference between strict (<< or >>) and non-strict (\leq or \geq) inequalities in absolute value problems?

Tip: When solving absolute value inequalities, always consider the two possible cases (positive and negative) that result from removing the absolute value bars.
