| ( | 353 100 | ÷ | 10000 | ) | ( | 1 10 | − | x | ) | = | x | ( | 3 10 | + | x | ) |
| 方程左边 = | 353 100 | ÷ | 10000 | × | ( | 1 10 | − | x | ) |
| = | 353 1000000 | ( | 1 10 | − | x | ) |
| = | 353 1000000 | × | 1 10 | − | 353 1000000 | x |
| = | 353 10000000 | − | 353 1000000 | x |
353 10000000 | − | 353 1000000 | x | = | x | ( | 3 10 | + | x | ) |
| 方程右边 = | x | × | 3 10 | + | x | x |
353 10000000 | − | 353 1000000 | x | = | 3 10 | x | + | x | x |
| x1=0 | ,它是方程的增解。 |
