To solve the equation \( y + 15 = 40 \), we need to isolate \( y \).
1. Subtract 15 from both sides of the equation:
\[
y + 15 - 15 = 40 - 15
\]
\[
y = 25
\]
Now, we need to find which number from the set \{15, 25, 35, 55\} makes the equation true. The solution we found is \( y = 25 \), which is indeed in the set.
Therefore, the answer is \( 25 \).
