| x | = | 33 100 | + | 1 10 | ( | 1 | − | x | + | 67 100 | ) |
| 方程右边 = | 33 100 | + | 1 10 | × | 1 | − | 1 10 | x | + | 1 10 | × | 67 100 |
| = | 33 100 | + | 1 10 | − | 1 10 | x | + | 67 1000 |
| = | 497 1000 | − | 1 10 | x |
| x | = | 497 1000 | − | 1 10 | x |
| x | + | 1 10 | x | = | 497 1000 |
11 10 | x | = | 497 1000 |
| x | = | 497 1000 | ÷ | 11 10 |
| = | 497 1000 | × | 10 11 |
| = | 497 100 | × | 1 11 |
| x | = | 497 1100 |
| x | = | 0.451818 |
