Theme: Sum Time

Author/Opus: This is the 72nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Enter a single digit from 1 to 9 into some cells so that the sum of digits in each Across entry equals the value given to the left of the entry, and the sum of digits in each Down entry equals the value given above the entry. No digit may be repeated within a single sum. Some cells may remain empty, and empty cells cannot be adjacent. Or see Serkan’s site for an example.

Answer String: Enter the values in the white cells in the marked rows from left to right, ignoring all black cells, and separating the rows with a comma. Use a capital ‘X’ for any blank cell.
