To determine which number from the set {15, 25, 35, 55} makes the equation y + 15 = 40 true, we substitute each number into the equation and check if it satisfies the equation.
1. Substitute 15:
15 + 15 = 40
30 = 40 (Not true)
2. Substitute 25:
25 + 15 = 40
40 = 40 (True)
3. Substitute 35:
35 + 15 = 40
50 = 40 (Not true)
4. Substitute 55:
55 + 15 = 40
70 = 40 (Not true)
Therefore, the number that makes the equation true is 25.
