The equation given is:

$5 + 2|2x + 4| = 9$

Let's solve it step by step.

Step 1: Isolate the absolute value expression

First, subtract 5 from both sides to isolate the absolute value term:

$2|2x + 4| = 9 - 5$

$2|2x + 4| = 4$

Step 2: Divide by 2

Next, divide both sides of the equation by 2:

$|2x + 4| = \frac{4}{2}$

$|2x + 4| = 2$

Step 3: Solve the absolute value equation

The absolute value equation $|2x + 4| = 2$ means there are two possible cases:

Case 1: $2x + 4 = 2$

Solve for $x$:

$2x + 4 = 2$ $2x = 2 - 4$ $2x = -2$ $x = \frac{-2}{2} = -1$

Case 2: $2x + 4 = -2$

Solve for $x$:

$2x + 4 = -2$ $2x = -2 - 4$ $2x = -6$ $x = \frac{-6}{2} = -3$

Step 4: Final solution

The two solutions are: $x = -1 \quad \text{or} \quad x = -3$
