| ( | x | − | 5000 | − | 1050 | ) | × | 1 10 | = | x | − | 10000 | − | 1050 |
| 方程左边 = | x | × | 1 10 | − | 5000 | × | 1 10 | − | 1050 | × | 1 10 |
| = | x | × | 1 10 | − | 500 | − | 105 |
| = | 1 10 | x | − | 605 |
1 10 | x | − | 605 | = | x | − | 10000 | − | 1050 |
| 方程右边 = | x | − | 11050 |
1 10 | x | − | 605 | = | x | − | 11050 |
1 10 | x | − | x | = | - | 11050 | + | 605 |
| - | 9 10 | x | = | - | 11050 | + | 605 |
| - | 9 10 | x | = | - | 10445 |
| 10445 | = | 9 10 | x |
9 10 | x | = | 10445 |
| x | = | 10445 | ÷ | 9 10 |
| = | 10445 | × | 10 9 |
| x | = | 104450 9 |
| x | = | 11605.555556 |
