Answer 3

To solve the equation |3x - 9| = 6, we need to consider both the positive and negative cases for the absolute value.

Case 1: 3x - 9 is positive If 3x - 9 is positive, then |3x - 9| = 3x - 9. So the equation becomes: 3x - 9 = 6

Now, let's solve for x: 3x = 6 + 9 3x = 15 x = 15 / 3 x = 5

Case 2: 3x - 9 is negative If 3x - 9 is negative, then |3x - 9| = -(3x - 9) = -3x + 9. So the equation becomes: -3x + 9 = 6

Now, let's solve for x: -3x = 6 - 9 -3x = -3 x = -3 / -3 x = 1

Thus, we have two solutions for x: x = 5 and x = 1.
