To solve the equation \( 2x + 4 = 16 \):

1. **Subtract 4** from both sides of the equation:
   \[
   2x + 4 - 4 = 16 - 4
   \]
   Simplifying this:
   \[
   2x = 12
   \]

2. **Divide both sides** by 2 to isolate \( x \):
   \[
   \frac{2x}{2} = \frac{12}{2}
   \]
   Simplifying this:
   \[
   x = 6
   \]

Thus, the solution is \( x = 6 \).
