| X | ÷ | 135 | − | 2 | = | 381 100000 | ( | X | + | 1000 | ) |
| 方程右边 = | 381 100000 | X | + | 381 100000 | × | 1000 |
| = | 381 100000 | X | + | 381 100 |
1 135 | X | − | 2 | = | 381 100000 | X | + | 381 100 |
1 135 | X | − | 381 100000 | X | = | 381 100 | + | 2 |
9713 2700000 | X | = | 381 100 | + | 2 |
9713 2700000 | X | = | 581 100 |
| X | = | 581 100 | ÷ | 9713 2700000 |
| = | 581 100 | × | 2700000 9713 |
| = | 581 | × | 27000 9713 |
