| x | ÷ | 3400 | = | ( | x | − | 8064 | ) | ÷ | 1300 |
| 方程右边 = | x | × | 1 1300 | − | 8064 | × | 1 1300 |
| = | x | × | 1 1300 | − | 2016 325 |
1 3400 | x | = | 1 1300 | x | − | 2016 325 |
1 3400 | x | − | 1 1300 | x | = | - | 2016 325 |
| - | 21 44200 | x | = | - | 2016 325 |
2016 325 | = | 21 44200 | x |
21 44200 | x | = | 2016 325 |
| x | = | 2016 325 | ÷ | 21 44200 |
| = | 2016 325 | × | 44200 21 |
| = | 96 | × | 136 |
| x | = | 13056 |
