Let x be the our required odd number.
Since the two integers are consecutive, the other number is x+2.
Given that, 2(greater number)=3(lesser number)-13.
2(x+2)=3x-13
2x+4=3x-13
Subtract 2x and add 13 on both sides,
2x+4-2x+13=3x-13-2x+13
17=x
Therefore x = 17.
The other number is x+2 = 19.
Hence the intergers are 17 and 19.

Let the lesser integer be x, then the next consecutive odd integer is (x+2).
Twice the greater (2(x+2)) is (=) 13 less than three times the lesser (3(x)-13)
Putting it all into an equation:
Simplify and solve for x.
Subtract 2x from both sides.
Add 13 to both sides.
The two consecutive odd integers are: 17 and 19
Check:
Twice 19 = 38
13 less than three times 17 = 51 - 13 = 38
