| 205 | × | 9 | × | 25 100 | = | P | × | 19 20 | − | 205 |
| Left side of the equation = | 1845 4 |
1845 4 | = | P | × | 19 20 | − | 205 |
| - | 19 20 | P | = | - | 205 | − | 1845 4 |
| - | 19 20 | P | = | - | 2665 4 |
2665 4 | = | 19 20 | P |
19 20 | P | = | 2665 4 |
| P | = | 2665 4 | ÷ | 19 20 |
| = | 2665 4 | × | 20 19 |
| = | 2665 | × | 5 19 |
| P | = | 13325 19 |
