53 50 | x | − | 19 20 | ( | 11000 | − | x | ) | = | 11000 | × | 49 50 |
| 方程左边 = | 53 50 | x | − | 19 20 | × | 11000 | + | 19 20 | x |
| = | 53 50 | x | − | 10450 | + | 19 20 | x |
| = | 201 100 | x | − | 10450 |
201 100 | x | − | 10450 | = | 11000 | × | 49 50 |
| 方程右边 = | 10780 |
201 100 | x | − | 10450 | = | 10780 |
201 100 | x | = | 10780 | + | 10450 |
201 100 | x | = | 21230 |
| x | = | 21230 | ÷ | 201 100 |
| = | 21230 | × | 100 201 |
| x | = | 2123000 201 |
| x | = | 10562.189055 |
