The sum of the digits is
1+x+3+5= A number multiple of 9 .
x+9= A number multiple of 9 .
x is a single-digit number, so
There are two possible cases for x i.e x=0 or x=9 .
Case 1 :
If x=0, x+9=0+9=9. ( So, 9 is divisible by 9 ).
Case 2:
If x=9, x+9=9+9=18. ( So, 18 is divisible by 9 ).
So, x=0 or 9 .
