The equation \( 8x + 18 = \_ (4x + 9) \) appears to have a missing part after the equals sign. Could you clarify if you're looking for the solution or if you want to fill in the blank with something specific?

In case you're looking to solve this equation, I'll assume it should look like this:
\[ 8x + 18 = (4x + 9) \]

If so, let's solve it step by step:

1. Start with the equation:
   \[ 8x + 18 = 4x + 9 \]

2. Subtract \( 4x \) from both sides to get:
   \[ 8x - 4x + 18 = 9 \]
   \[ 4x + 18 = 9 \]

3. Subtract 18 from both sides:
   \[ 4x = 9 - 18 \]
   \[ 4x = -9 \]

4. Finally, divide by 4:
   \[ x = \frac{-9}{4} \]
   \[ x = -\frac{9}{4} \]

Thus, the solution is:
\[
x = -\frac{9}{4}
\]
