Math Problem Statement

|2x-5|<11

Solution

To solve the inequality 2x5<11|2x - 5| < 11, we need to split it into two cases based on the definition of absolute value:

Case 1: Positive scenario

2x5<112x - 5 < 11

  1. Add 5 to both sides: 2x<162x < 16

  2. Divide by 2: x<8x < 8

Case 2: Negative scenario

(2x5)<11-(2x - 5) < 11

This simplifies to: 2x5>112x - 5 > -11

  1. Add 5 to both sides: 2x>62x > -6

  2. Divide by 2: x>3x > -3

Final solution:

Combining both cases, we get: 3<x<8-3 < x < 8

Thus, the solution is x(3,8)x \in (-3, 8).

Would you like more details on any step? Here are some related questions to deepen understanding:

  1. How do we solve absolute value equations?
  2. What happens when we solve an absolute value inequality involving "greater than"?
  3. How do you graph the solution 3<x<8-3 < x < 8?
  4. What are the implications of dividing inequalities by negative numbers?
  5. Can we use a different method to solve this inequality?

Tip: Always remember that solving absolute value inequalities involves splitting the expression into two cases: one for the positive scenario and one for the negative.
