| 方程左边 = | 1093000 | − | 1093000 | × | 3 50 | + | x | × | 3 50 | − | x |
| = | 1093000 | − | 65580 | + | x | × | 3 50 | − | x |
| = | 1027420 | − | 47 50 | x |

| 方程右边 = | 43720 |
| 1027420 | − | 47 50 | x | = | 43720 |
| - | 47 50 | x | = | 43720 | − | 1027420 |
| - | 47 50 | x | = | - | 983700 |
| 983700 | = | 47 50 | x |
47 50 | x | = | 983700 |
| x | = | 983700 | ÷ | 47 50 |
| = | 983700 | × | 50 47 |
