Math Problem Statement

|3x - 4| = 2

Solution

The given equation is:

3x4=2|3x - 4| = 2

Step-by-step solution:

  1. Definition of absolute value: The absolute value equation can be broken into two cases: 3x4=2or3x4=23x - 4 = 2 \quad \text{or} \quad 3x - 4 = -2

  2. Solving the first case: 3x4=23x - 4 = 2 Add 4 to both sides: 3x=63x = 6 Divide by 3: x=2x = 2

  3. Solving the second case: 3x4=23x - 4 = -2 Add 4 to both sides: 3x=23x = 2 Divide by 3: x=23x = \frac{2}{3}

Final solution:

The solution to the equation is: x=2orx=23x = 2 \quad \text{or} \quad x = \frac{2}{3}

Let me know if you need further details or have any questions.
