Digit in the thousands place

If 1 is in the ones place and 3 is in the hundreds place
Digit in the tens place for scenario 1
= 26 - 8 - 3 - 1
= 14 (✗)
If 2 is in the ones place and 6 is in the hundreds place
Digit in the tens place for scenario 2
= 26 - 8 - 6 - 1
= 10 (✗)
If 3 is in the ones place and 9 is in the hundreds place
Digit in the tens place for scenario 3
= 26 - 8 - 9 - 1
= 6 (✓) (Digit in the tens place must be single digit.)
