Answer 1

For the equation 2x + 5 = 31, we need to find x.

Substitute each number from the set {6, 13, 18, 26} into the equation and see which one makes it true:

1. If x = 6: 2(6) + 5 = 12 + 5 = 17 (not equal to 31)
2. If x = 13: 2(13) + 5 = 26 + 5 = 31 (equal to 31)
3. If x = 18: 2(18) + 5 = 36 + 5 = 41 (not equal to 31)
4. If x = 26: 2(26) + 5 = 52 + 5 = 57 (not equal to 31)

Therefore, the number 13 from the set {6, 13, 18, 26} is the one that makes the equation true.
