Find all 6-digit numbers x with the following property:
If the first digit in x is deleted and added after the 5 other digits, you get a number that is 3 times as large as x.
For instance, the number x=158249 gets turned into 582491.
The number x=158249 does not meet the condition, because 3*158249 ≠ 582491
I hope that someone can help me with this problem - I have no idea how to solve it..
