I'm just guessing, but I think you mean:
My number has a ones digit that is double the tens digit. The sum of the digits is nine.
Going under that assumption, let 
represent the tens digit, then 
must represent the ones digit.
Solve for to get the tens digit. Double it to get the ones digit. Construct your number.
