| ( | 322 | × | 267 500 | + | x | ) | ÷ | ( | 322 | + | x | ) | = | 3 5 |
| 方程两边同时乘以: | ( | 322 | + | x | ) |
| ( | 322 | × | 267 500 | + | x | ) | = | 3 5 | ( | 322 | + | x | ) |
| 322 | × | 267 500 | + | x | = | 3 5 | ( | 322 | + | x | ) |

42987 250 | + | x | = | 966 5 | + | 3 5 | x |
| x | − | 3 5 | x | = | 966 5 | − | 42987 250 |
2 5 | x | = | 966 5 | − | 42987 250 |
2 5 | x | = | 5313 250 |
| x | = | 5313 250 | ÷ | 2 5 |
| = | 5313 250 | × | 5 2 |
| = | 5313 50 | × | 1 2 |
