| 1 | = | 834 125 | X | ÷ | ( | X | + | 1400 | ) |
| 方程两边同时乘以: | ( | X | + | 1400 | ) |
| 1 | ( | X | + | 1400 | ) | = | 834 125 | X |
| 1 | X | + | 1 | × | 1400 | = | 834 125 | X |
| 1 | X | + | 1400 | = | 834 125 | X |
| 1 | X | − | 834 125 | X | = | - | 1400 |
| - | 709 125 | X | = | - | 1400 |
| 1400 | = | 709 125 | X |
709 125 | X | = | 1400 |
| X | = | 1400 | ÷ | 709 125 |
| = | 1400 | × | 125 709 |
| X | = | 175000 709 |
