Two identical five-digits

We have two identical five-digit numbers, but we don't know which ones. When we write one before the first and after the second one we get two six-digit numbers, one of which is three times the other. What are the numbers?

Correct answer:

x =  42857

Step-by-step explanation:

3 (100000+x)=10 x+1  7x=299999  x=42857
