Math Problem Statement

|4x - 2| ≤ 10

Solution

The inequality in the image is:

4x210|4x - 2| \leq 10

This is an absolute value inequality, which can be solved in two cases:

  1. 4x2104x - 2 \leq 10
  2. (4x2)10-(4x - 2) \leq 10 (or equivalently 4x2104x - 2 \geq -10)

Let's solve each case:

Case 1: 4x2104x - 2 \leq 10

Add 2 to both sides: 4x124x \leq 12 Now, divide both sides by 4: x3x \leq 3

Case 2: 4x2104x - 2 \geq -10

Add 2 to both sides: 4x84x \geq -8 Now, divide both sides by 4: x2x \geq -2

Combined solution:

The solution to the inequality is: 2x3-2 \leq x \leq 3

This means the values of xx lie between 2-2 and 33, inclusive.

Here are some related questions to explore further:

  1. How do we graph the solution 2x3-2 \leq x \leq 3?
  2. What changes if the inequality were 4x210|4x - 2| \geq 10 instead?
  3. How do we handle absolute value inequalities when there is a strict inequality 4x2<10|4x - 2| < 10?
  4. What is the general method for solving absolute value equations or inequalities?
  5. Can we express this inequality solution in interval notation?

Tip: When solving absolute value inequalities, always split the problem into two cases (positive and negative).
