Math Problem Statement

Solve. If there is more than one solution, separate them with a comma. If there are no solutions, enter DNE. −5 − 3| −8x + 6 | = −29

Solution

To solve the equation:

538x+6=29-5 - 3| -8x + 6 | = -29

we'll first isolate the absolute value term.

Step 1: Isolate the Absolute Value Term

  1. Start by moving 5-5 to the other side: 38x+6=29+5-3| -8x + 6 | = -29 + 5 38x+6=24-3| -8x + 6 | = -24

  2. Next, divide both sides by 3-3: 8x+6=8| -8x + 6 | = 8

Step 2: Set Up Two Cases for the Absolute Value

Since 8x+6=8| -8x + 6 | = 8, we can write two separate equations:

Case 1:

8x+6=8-8x + 6 = 8

  1. Subtract 6 from both sides: 8x=2-8x = 2
  2. Divide by 8-8: x=14x = -\frac{1}{4}

Case 2:

8x+6=8-8x + 6 = -8

  1. Subtract 6 from both sides: 8x=14-8x = -14
  2. Divide by 8-8: x=74x = \frac{7}{4}

Solution

The solutions are: x=14,74x = -\frac{1}{4}, \frac{7}{4}
