| X | ÷ | 141 | − | ( | 95 | − | X | ) | ÷ | 1000 | = | 457 1000 |
| 方程左边 = | 1 141 | X | − | 95 | × | 1 1000 | + | X | × | 1 1000 |
| = | 1 141 | X | − | 19 200 | + | X | × | 1 1000 |
| = | 1141 141000 | X | − | 19 200 |
1141 141000 | X | − | 19 200 | = | 457 1000 |
1141 141000 | X | = | 457 1000 | + | 19 200 |
1141 141000 | X | = | 69 125 |
| X | = | 69 125 | ÷ | 1141 141000 |
| = | 69 125 | × | 141000 1141 |
| = | 69 | × | 1128 1141 |
| X | = | 77832 1141 |
