| ( | 218 | + | x | ) | ÷ | ( | 3396 | + | x | ) | = | 33 500 |
| 方程两边同时乘以: | ( | 3396 | + | x | ) |
| ( | 218 | + | x | ) | = | 33 500 | ( | 3396 | + | x | ) |
| 218 | + | x | = | 33 500 | ( | 3396 | + | x | ) |
| 218 | + | x | = | 33 500 | × | 3396 | + | 33 500 | x |
| 218 | + | x | = | 28017 125 | + | 33 500 | x |
| x | − | 33 500 | x | = | 28017 125 | − | 218 |
467 500 | x | = | 28017 125 | − | 218 |
467 500 | x | = | 767 125 |
| x | = | 767 125 | ÷ | 467 500 |
| = | 767 125 | × | 500 467 |
| = | 767 | × | 4 467 |
