| ( | x | − | 2649809 10000 | ) | ÷ | x | = | - | 99 5000 |
| 方程两边同时乘以: | x |
| ( | x | − | 2649809 10000 | ) | = | - | 99 5000 | x |
| x | − | 2649809 10000 | = | - | 99 5000 | x |
| x | + | 99 5000 | x | = | 2649809 10000 |
5099 5000 | x | = | 2649809 10000 |
| x | = | 2649809 10000 | ÷ | 5099 5000 |
| = | 2649809 10000 | × | 5000 5099 |
