| ( | 74556 | + | X | ) | ÷ | ( | 58646 | − | X | ) | = | 3 2 |
| 方程两边同时乘以: | ( | 58646 | − | X | ) |
| ( | 74556 | + | X | ) | = | 3 2 | ( | 58646 | − | X | ) |
| 74556 | + | X | = | 3 2 | ( | 58646 | − | X | ) |
| 74556 | + | X | = | 3 2 | × | 58646 | − | 3 2 | X |
| 74556 | + | X | = | 87969 | − | 3 2 | X |
| X | + | 3 2 | X | = | 87969 | − | 74556 |
5 2 | X | = | 87969 | − | 74556 |
5 2 | X | = | 13413 |
| X | = | 13413 | ÷ | 5 2 |
| = | 13413 | × | 2 5 |
| X | = | 26826 5 |
| X | = | 5365.2 |
