| x | = | 9 500000 | ( | 1 10 | − | x | ) | ÷ | 1 500 | + | x |
| 方程右边 = | 9 1000 | ( | 1 10 | − | x | ) | + | x |
| x | = | 9 1000 | ( | 1 10 | − | x | ) | + | x |
| 方程右边 = | 9 1000 | × | 1 10 | − | 9 1000 | x | + | x |
| = | 9 10000 | − | 9 1000 | x | + | x |
| = | 9 10000 | + | 991 1000 | x |
| x | = | 9 10000 | + | 991 1000 | x |
| x | − | 991 1000 | x | = | 9 10000 |
9 1000 | x | = | 9 10000 |
| x | = | 9 10000 | ÷ | 9 1000 |
| = | 9 10000 | × | 1000 9 |
| = | 1 10 | × | 1 |
| x | = | 1 10 |
