I don't get the question. Two different numbers share a digit. "But in reverse order"? What does reverse order mean? What is being reversed?

as in 346 and 643
The difference will always be divisible by 9.

we can work with a 4-digit number, but the logic works for any number of digits. If the digits are

a,b,c,d then the value is
abcd = 1000a+100b+10c+d
dcba = 1000d+100c+10b+a

abcd-dcba =
999a + 90b - 90c - 999d

The difference between three-fifths of a number and 7 is -36.
