| ( | x | − | 735941 25 | ) | ÷ | x | = | 387 2000 |
| 方程两边同时乘以: | x |
| ( | x | − | 735941 25 | ) | = | 387 2000 | x |
| x | − | 735941 25 | = | 387 2000 | x |
| x | − | 387 2000 | x | = | 735941 25 |
1613 2000 | x | = | 735941 25 |
| x | = | 735941 25 | ÷ | 1613 2000 |
| = | 735941 25 | × | 2000 1613 |
| = | 735941 | × | 80 1613 |
| x | = | 58875280 1613 |
| x | = | 36500.483571 |
