Using substitution, which number from the set {15, 25, 35, 55} makes the equation y+15=40 true?(1 point) Responses 35 35 15 15 55 55 25

To solve the equation y + 15 = 40 using substitution, we need to find the number from the set {15, 25, 35, 55} that satisfies the equation.

We can substitute each number into the equation and check if it makes the equation true.

Substituting 15:
15 + 15 = 30 (not equal to 40)

Substituting 25:
25 + 15 = 40 (equal to 40)

Substituting 35:
35 + 15 = 50 (not equal to 40)

Substituting 55:
55 + 15 = 70 (not equal to 40)

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