To solve the equation 2x + 5 = 31 using substitution, we can substitute each number from the given set into the equation and see which one makes the equation true.
1) Substitute 6:
2(6) + 5 = 12 + 5 = 17 (Not equal to 31)
2) Substitute 13:
2(13) + 5 = 26 + 5 = 31 (Equal to 31, this number makes the equation true)
3) Substitute 18:
2(18) + 5 = 36 + 5 = 41 (Not equal to 31)
4) Substitute 26:
2(26) + 5 = 52 + 5 = 57 (Not equal to 31)
Thus, the number from the given set that makes the equation true is 13.
Using substitution, which number from the set {6, 13, 18, 26} makes the equation 2x 5=31 true?(1 point) Responses 13 13 26 26 18 18 6
