Math Problem Statement

|4x| + 5 = 13

Solution

The equation in the image is:

4x+5=13|4x| + 5 = 13

Step 1: Isolate the absolute value term

4x=135|4x| = 13 - 5 4x=8|4x| = 8

Step 2: Solve for 4x4x in both cases (absolute value equation splits into two cases)

  1. 4x=84x = 8 x=84=2x = \frac{8}{4} = 2

  2. 4x=84x = -8 x=84=2x = \frac{-8}{4} = -2

Final Answer:

The solutions are: x=2orx=2x = 2 \quad \text{or} \quad x = -2
