It is long and hairy but it is one step: Code: | *-----------------------------------------------------------------------------*
| 2 157 17 | 457 3 8 | 6 149 149 |
| 359 8 69 | 456 46 1 | 234 234 7 |
| 37 167 4 | 67 9 2 | 13 8 5 |
|-------------------------+-------------------------+-------------------------|
| 4 17 17 | 3 25 6 | 8 259 29 |
| 6 3 5 | 249 8 49 | 124 7 124 |
| 8 9 2 | 1 45 7 | 345 3456 346 |
|-------------------------+-------------------------+-------------------------|
| 1 256 69 | 8 246 3459 | 7 23456 2346 |
| 579 2567 8 | 2469 17 3459 | 123459 123456 12346 |
| 579 4 3 | 269 17 59 | 1259 1256 8 |
*-----------------------------------------------------------------------------*
(2)r4c5 = (2-6)r7c5 = r2c5 - (6-9)r2c3 - r7c3 = r7c6 - r5c6 = (9-2)r5c4 = (2)r4c5;
r4c5=2
