To solve the equation \( 2x + 5 = 9 \), follow these steps:

1. **Subtract 5 from both sides** of the equation:
   \[
   2x + 5 - 5 = 9 - 5
   \]
   Simplifying this gives:
   \[
   2x = 4
   \]

2. **Divide both sides by 2** to isolate \( x \):
   \[
   \frac{2x}{2} = \frac{4}{2}
   \]
   Simplifying this gives:
   \[
   x = 2
   \]

So, the solution is \( x = 2 \).
