| 方程左边 = | 34969 1000 | x | + | 18483 500 | × | 1 | − | 18483 500 | x |
| = | 34969 1000 | x | + | 18483 500 | − | 18483 500 | x |
| = | - | 1997 1000 | x | + | 18483 500 |
| - | 1997 1000 | x | + | 18483 500 | = | 71 2 |
| - | 1997 1000 | x | = | 71 2 | − | 18483 500 |
| - | 1997 1000 | x | = | - | 733 500 |
733 500 | = | 1997 1000 | x |
1997 1000 | x | = | 733 500 |
| x | = | 733 500 | ÷ | 1997 1000 |
| = | 733 500 | × | 1000 1997 |
| = | 733 | × | 2 1997 |
