Let's say your 2 digit number is XY which is 10X + Y. You have 2 equations to work with:
X+Y=5 or X=5-Y
and
10X + Y = 10Y + X - 27 or 9X = 9Y - 27 or X = Y - 3
Substitute 5-Y for X in the 2nd equation:
5 - Y = Y - 3
8 = 2Y
Y = 4
Therefore X=1; your original is 14 and the reverse is 41. Just as luca-deltodesco said.
