Using substitution, we can replace y with each number from the given set and check which one makes the equation true.

For y = 35:
35 + 15 = 40
50 = 40 (not true)

For y = 55:
55 + 15 = 40
70 = 40 (not true)

For y = 25:
25 + 15 = 40
40 = 40 (true)

For y = 15:
15 + 15 = 40
30 = 40 (not true)

Therefore, the number from the set {15, 25, 35, 55} that makes the equation y + 15 = 40 true is 25.
