Math Problem Statement

Solve the inequality |3 - 2x| < 5 and choose the correct answer from the options provided.

Solution

The problem you provided asks to solve the inequality 32x<5|3 - 2x| < 5 and choose the correct answer from the given options.

Let's solve the inequality step by step:

  1. Start with the absolute value inequality: 32x<5|3 - 2x| < 5

  2. Rewrite as a compound inequality (because of the absolute value): 5<32x<5-5 < 3 - 2x < 5

  3. Solve the compound inequality:

    • First, subtract 3 from all parts of the inequality: 53<2x<53-5 - 3 < -2x < 5 - 3 8<2x<2-8 < -2x < 2
    • Next, divide by 2-2 and reverse the inequality signs (since we are dividing by a negative number): 82>x>22\frac{-8}{-2} > x > \frac{2}{-2} 4>x>14 > x > -1
    • This simplifies to: 1<x<4-1 < x < 4

The solution is that xx is between 1-1 and 44, which corresponds to option C: 1<x<4-1 < x < 4.

Would you like more details on the solution, or do you have any specific questions? Here are 5 related questions to explore further:

  1. How do you solve absolute value inequalities in general?
  2. Why do we reverse the inequality sign when dividing by a negative number?
  3. How would the solution change if the inequality were 32x>5|3 - 2x| > 5?
  4. What is the difference between "and" and "or" solutions in compound inequalities?
  5. How do we graph the solution 1<x<4-1 < x < 4 on a number line?

Tip: When solving inequalities with absolute values, always break them into two cases (positive and negative) before solving.
