Math Problem Statement

Select all the values of x that are solutions of |3x - 6| = 12.

Solution

We are given the absolute value equation:

3x6=12|3x - 6| = 12

To solve this, we need to consider two cases because the absolute value of an expression can be equal to a number if the expression inside is either positive or negative.

Case 1: 3x6=123x - 6 = 12

Solve for xx:

3x6=123x - 6 = 12

Add 6 to both sides:

3x=183x = 18

Divide by 3:

x=6x = 6

Case 2: 3x6=123x - 6 = -12

Solve for xx:

3x6=123x - 6 = -12

Add 6 to both sides:

3x=63x = -6

Divide by 3:

x=2x = -2

Thus, the solutions are x=6x = 6 and x=2x = -2.

Final Answer

The correct values of xx from the choices are:

  • C. x=2x = -2
  • E. x=6x = 6

  2. What are the general steps for solving equations involving absolute values?
  3. What happens if the right-hand side of an absolute value equation is negative?
  4. Can absolute value equations have more than two solutions?
  5. How can you verify if a solution is correct?

Tip: Always check the two cases when solving absolute value equations!
