This is the Sujiao version.

I do it myself and want to !! Judgment Roll!! Envy!! Prepare for the !!

x=ab

y=baba=2ab

10b+a=20a+2b

8b=19a

a=8b/19

a, b are integers.

Then b must be a multiple of 19 is not possible.

There is no solution, there is no such number in two digits.

Let x=10a+b, then y=10b+a

a, b are 0 9 positive integers).

20a+2b=10b+a

19a=8b

To conclude that this number should not exist.

That is, to take out the unsolvable problem for others to do, as if you are very smart

x:10a+b

y:10b+a

2(10a+b)=10b+a

y is a multiple of 2 and a may beA is not 0, so B cannot be 5, if A is 6 or 8, 2x>100, Y is a two-digit number, so it is not true, so A is 2 or 4, if A is 2, B > 5, then 255, then 45B<5 then 40, in summary, there is no solution.

Why have people been asking this question for the past two days, knowing that there is no answer.
