| x | ÷ | ( | x | + | 9 5 | ) | = | 631 1000 | ÷ | 33 10 |
| 方程两边同时乘以: | ( | x | + | 9 5 | ) |
| x | = | 631 1000 | ÷ | 33 10 | × | ( | x | + | 9 5 | ) |
| x | = | 631 1000 | ÷ | 33 10 | × | x | + | 631 1000 | ÷ | 33 10 | × | 9 5 |
| x | = | 631 3300 | x | + | 1893 5500 |
| x | − | 631 3300 | x | = | 1893 5500 |
2669 3300 | x | = | 1893 5500 |
| x | = | 1893 5500 | ÷ | 2669 3300 |
| = | 1893 5500 | × | 3300 2669 |
| = | 1893 5 | × | 3 2669 |
| x | = | 5679 13345 |
