| 1061770 | × | 51 100 | − | x | = | 1 2 | ( | 1061770 | − | x | ) |
| 方程左边 = | 5415027 10 | − | x |
5415027 10 | − | x | = | 1 2 | ( | 1061770 | − | x | ) |
| 方程右边 = | 1 2 | × | 1061770 | − | 1 2 | x |
| = | 530885 | − | 1 2 | x |
5415027 10 | − | x | = | 530885 | − | 1 2 | x |
| - | x | + | 1 2 | x | = | 530885 | − | 5415027 10 |
| - | 1 2 | x | = | 530885 | − | 5415027 10 |
| - | 1 2 | x | = | - | 106177 10 |
106177 10 | = | 1 2 | x |
1 2 | x | = | 106177 10 |
| x | = | 106177 10 | ÷ | 1 2 |
| = | 106177 10 | × | 2 |
| = | 106177 5 | × | 1 |
| x | = | 106177 5 |
