Math Problem Statement

Solve |2x - 3| < 5 and give your answer as an interval.

Solution

The given inequality is 2x3<5|2x - 3| < 5.

To solve it, we need to remove the absolute value by breaking it into two inequalities:

5<2x3<5-5 < 2x - 3 < 5

Step 1: Solve the left part

5<2x3-5 < 2x - 3 Add 3 to both sides: 5+3<2x-5 + 3 < 2x 2<2x-2 < 2x Now, divide by 2: 1<x-1 < x

Step 2: Solve the right part

2x3<52x - 3 < 5 Add 3 to both sides: 2x<82x < 8 Now, divide by 2: x<4x < 4

Final result:

The solution is: 1<x<4-1 < x < 4 In interval notation, the solution is: (1,4)(-1, 4)

Here are some related questions:

  1. What happens if the inequality sign is reversed?
  2. How do we handle absolute value inequalities with a "greater than" symbol?
  3. Can you describe a real-life scenario where absolute value inequalities apply?
  4. What is the graphical representation of this solution?
  5. How would the solution change if the inequality had been 2x35|2x - 3| \leq 5?

Tip: Always remember to break absolute value inequalities into two cases—positive and negative—when solving.
