Math Problem Statement

|2x + 4| = 8

Solution

The equation in the image is:

2x+4=8|2x + 4| = 8

To solve this absolute value equation, follow these steps:

Step 1: Set up two separate cases since the absolute value expression can be either positive or negative.

Case 1:

2x+4=82x + 4 = 8 Solve for xx: 2x=842x = 8 - 4 2x=42x = 4 x=2x = 2

Case 2:

2x+4=82x + 4 = -8 Solve for xx: 2x=842x = -8 - 4 2x=122x = -12 x=6x = -6

Final Answer:

The solutions are x=2x = 2 and x=6x = -6.

Conclusion:

The correct option is the one that shows x=2x = 2 and x=6x = -6.
