1917 25 | − | 5 2 | ( | 41 5 | x | + | 6 | ) | = | 26 5 | x |
| 方程左边 = | 1917 25 | − | 5 2 | × | 41 5 | x | − | 5 2 | × | 6 |
| = | 1917 25 | − | 41 2 | x | − | 15 |
| = | 1542 25 | − | 41 2 | x |
1542 25 | − | 41 2 | x | = | 26 5 | x |
| - | 41 2 | x | − | 26 5 | x | = | - | 1542 25 |
| - | 257 10 | x | = | - | 1542 25 |
1542 25 | = | 257 10 | x |
257 10 | x | = | 1542 25 |
| x | = | 1542 25 | ÷ | 257 10 |
| = | 1542 25 | × | 10 257 |
| = | 1542 5 | × | 2 257 |
| x | = | 3084 1285 |
