Answer 1

Let's substitute each number from the set into the equation and see which one makes it true.

For 6:
2(6) + 5 = 12 + 5 = 17, which is not equal to 31.

For 13:
2(13) + 5 = 26 + 5 = 31, which is equal to 31.

For 18:
2(18) + 5 = 36 + 5 = 41, which is not equal to 31.

For 26:
2(26) + 5 = 52 + 5 = 57, which is not equal to 31.

Therefore, the number from the set that makes the equation true is 13.
