**tchrwill**, Wednesday, February 2, 2011 at 10:10amLet the two digit number be 10A + B.

Then, from "If the tens digit of a two-digit number is subtracted from the units digit, the difference is 8.", or

B - A = 8.

From "The number with the digits reversed is 10 more than nine times the units digit of the original number.", 10B + A = 9B + 10.

Substituting A = B - 8 into 10B + A = 9B + 10 yields 10B + B - 8 = 9B + 10 or 11B - 8 = 9B + 10 or 2B = 18 making B = 9.

From B - A = 8, 9 - A = 8 making A = 1 or the number = 19.
