.
Let x = 1st consecutive odd integer
then
x+2 = greater consecutive odd integer
.
2(x+2) = 3x-13
2x+4 = 3x-13
4 = x-13
17 = x
.
Greater integer:
x+2 = 17+2 = 19
.
Therefore, the two integers are 17 and 19

Let the smaller of the 2 numbers be S
Then the greater number would be S + 2
Since twice the greater of the 2 odd integers is 13 less than three times the lesser, we will have:
2(S + 2) = 3S - 13
2S + 4 = 3S - 13
2S - 3S = - 13 - 4
- S = - 17
Therefore, the smaller odd integer is and the larger consecutive odd integer is (17 + 2)

Check
---------
Twice the greater integer, 19, is 38 (2 * 19)
3 times the lesser integer is 51 (3 * 17)
Twice the greater integer, or 38 is 13 less than 3 times the lesser integer, or 51 (51 - 13 = 38)
