To solve the equation \( 2d + 3 = 13 \):

1. Subtract 3 from both sides:
   \[
   2d + 3 - 3 = 13 - 3
   \]
   \[
   2d = 10
   \]

2. Divide both sides by 2:
   \[
   \frac{2d}{2} = \frac{10}{2}
   \]
   \[
   d = 5
   \]

So, \( d = 5 \).

Would you like more details or have any questions? Here are some related problems:

1. Solve \( 3d + 5 = 20 \).
2. Solve \( 4d - 7 = 9 \).
3. What is \( 5d + 2 = 17 \)?
4. Find \( d \) if \( 6d + 3 = 21 \).
5. Solve for \( d \) in \( 8d - 4 = 20 \).

**Tip:** Always perform the same operation on both sides of the equation to maintain equality.
