Using substitution, which number from the set {15, 25, 35, 55} makes the equation y+15=40 true?(1 point) Responses 55 55 35 35 15 15 25
To solve the equation y + 15 = 40 using substitution, we substitute each number from the given set into the equation and see which one satisfies the equation.
For 15:
15 + 15 = 30, which is not equal to 40
For 25:
25 + 15 = 40, which is equal to 40
For 35:
35 + 15 = 50, which is not equal to 40
For 55:
55 + 15 = 70, which is not equal to 40
So, the number from the set {15, 25, 35, 55} that makes the equation y + 15 = 40 true is 25.
