Please stop shouting. Typing in all caps is the electronic equivalent of shouting and is both rude and annoying.

Let x represent the 10s digit and let y represent the 1s digit. Then the number is and the number with the digits reversed is

The sum of the digits is 14:



Reversing the digits subtracted from the original number:



Now you have a system of two equations in two variables. Solve the system. The x value will be the 10s digit of the original number and the y value will be the 1s digit.
