Answer 3

Solving the Absolute Value Equation |2x + 4| = 8

To solve the absolute value equation |2x + 4| = 8, we'll need to consider both the positive and negative cases for the expression inside the absolute value.

Positive Case: We start by setting the expression inside the absolute value equal to the positive value of 8: 2x + 4 = 8

Negative Case: Then, we set the expression inside the absolute value equal to the negative value of 8 and solve for x: 2x + 4 = -8

Let's solve for x in both cases.

Positive Case: Starting with 2x + 4 = 8: ``` 2x + 4 = 8 2x = 8 - 4 2x = 4 x = 4 / 2 x = 2 ``` So, in the positive case, x = 2.

Negative Case: Now, solving 2x + 4 = -8: ``` 2x + 4 = -8 2x = -8 - 4 2x = -12 x = -12 / 2 x = -6 ``` In the negative case, x = -6.

Therefore, the solutions to the absolute value equation |2x + 4| = 8 are x = 2 and x = -6.
