| ( | 260 | × | 63 | − | x | ) | × | 19 20 | = | 271263 20 |
| Left side of the equation = | 260 | × | 63 | × | 19 20 | − | x | × | 19 20 |
| = | 15561 | − | x | × | 19 20 |
| 15561 | − | 19 20 | x | = | 271263 20 |
| - | 19 20 | x | = | 271263 20 | − | 15561 |
| - | 19 20 | x | = | - | 39957 20 |
39957 20 | = | 19 20 | x |
19 20 | x | = | 39957 20 |
| x | = | 39957 20 | ÷ | 19 20 |
| = | 39957 20 | × | 20 19 |
| = | 2103 | × | 1 |
| x | = | 2103 |
