| 方程右边 = | 181 1000 | + | 1 10 | × | 1 | − | 1 10 | x | + | 1 10 | × | 819 1000 |
| = | 181 1000 | + | 1 10 | − | 1 10 | x | + | 819 10000 |
| = | 3629 10000 | − | 1 10 | x |
| x | = | 3629 10000 | − | 1 10 | x |
| x | + | 1 10 | x | = | 3629 10000 |
11 10 | x | = | 3629 10000 |
| x | = | 3629 10000 | ÷ | 11 10 |
| = | 3629 10000 | × | 10 11 |
| = | 3629 1000 | × | 1 11 |
| x | = | 3629 11000 |
