a two-digit number is such that the tens digit is at least 5 more than twice the units digit. find all positive integers.

Let the tens digit be T, and the units digit, U
Then:

Let U = 0

, or T = 5, 6, 7, 8, or 9
Numbers would then be

Let U = 1

, or T = 7, 8, or 9
Numbers would then be:

Let U = 2

, or T = 9
Number would then be:

The number could be any of the above 9
