| X | ÷ | 141 | − | 1 10 | = | 261 50000 | ( | 100 | + | X | ) |
| 方程右边 = | 261 50000 | × | 100 | + | 261 50000 | X |
| = | 261 500 | + | 261 50000 | X |
1 141 | X | − | 1 10 | = | 261 500 | + | 261 50000 | X |
1 141 | X | − | 261 50000 | X | = | 261 500 | + | 1 10 |
13199 7050000 | X | = | 261 500 | + | 1 10 |
13199 7050000 | X | = | 311 500 |
| X | = | 311 500 | ÷ | 13199 7050000 |
| = | 311 500 | × | 7050000 13199 |
| = | 311 | × | 14100 13199 |
