Math Problem Statement

Solve the inequality |3x - 5| > 1 and express the solution in interval notation.

Solution

We are tasked with solving the inequality 3x5>1|3x - 5| > 1 and expressing the solution in interval notation.

Step 1: Break the absolute value inequality into two cases

The inequality 3x5>1|3x - 5| > 1 means:

3x5>1or3x5<13x - 5 > 1 \quad \text{or} \quad 3x - 5 < -1

Step 2: Solve each inequality

Case 1: 3x5>13x - 5 > 1

3x>6x>23x > 6 \quad \Rightarrow \quad x > 2

Case 2: 3x5<13x - 5 < -1

3x<4x<433x < 4 \quad \Rightarrow \quad x < \frac{4}{3}

Step 3: Combine the results

The solution to 3x5>1|3x - 5| > 1 is where x>2x > 2 or x<43x < \frac{4}{3}.

In interval notation, this is: (,43)(2,)(-\infty, \frac{4}{3}) \cup (2, \infty)

Final Solution:

(,43)(2,)(-\infty, \frac{4}{3}) \cup (2, \infty)

Here are 5 questions to deepen your understanding:

  1. What are the rules for solving absolute value inequalities?
  2. How does splitting an absolute value inequality into two cases work?
  3. Why is the solution expressed as two separate intervals?
  4. How would the solution change if the inequality were 3x51|3x - 5| \leq 1?
  5. How can you verify the solution graphically?

Tip: When solving absolute value inequalities, always double-check the critical points by testing values in each interval.
