| ( | v | − | 94 5 | ) | ( | - | 143 5 | ) | = | 94 5 | v |
| 方程左边 = | v | ( | - | 143 5 | ) | − | 94 5 | ( | - | 143 5 | ) |
| = | - | v | × | 143 5 | − | 94 5 | ( | - | 143 5 | ) |
| = | - | 143 5 | v | + | 94 5 | × | 143 5 |
| = | - | 143 5 | v | + | 13442 25 |
| - | 143 5 | v | + | 13442 25 | = | 94 5 | v |

| - | 237 5 | v | = | - | 13442 25 |
13442 25 | = | 237 5 | v |
237 5 | v | = | 13442 25 |
| v | = | 13442 25 | ÷ | 237 5 |
| = | 13442 25 | × | 5 237 |
