Write the 2 digit numbers that matches the clues my number has tens digit that 8 more that one's digit. zero is not one my digits

The answer is 91 because the tens place has to be 8 more so in the 80's, 8 would be 8 more than 0 and 0 is not one of the digits and it's a 2 digit number so it can't go to the 100's so 91 is the best answer. I hope this helped you
