To solve the equation y+15=40 using substitution, we need to substitute each number from the set {15, 25, 35, 55} for y and see which one makes the equation true.
If we substitute y=25, we get 25+15=40, which is true.
Therefore, the number from the set {15, 25, 35, 55} that makes the equation y+15=40 true is 25.
Using substitution, which number from the set {15, 25, 35, 55} makes the equation y+15=40 true?(1 point)
