| ( | x | − | 156169 100 | ) | ÷ | x | = | 117 5000 |
| 方程两边同时乘以: | x |
| ( | x | − | 156169 100 | ) | = | 117 5000 | x |
| x | − | 156169 100 | = | 117 5000 | x |
| x | − | 117 5000 | x | = | 156169 100 |
4883 5000 | x | = | 156169 100 |
| x | = | 156169 100 | ÷ | 4883 5000 |
| = | 156169 100 | × | 5000 4883 |
| = | 156169 | × | 50 4883 |
| x | = | 7808450 4883 |
| x | = | 1599.109154 |
