| 方程左边 = | 22 5 | − | ( | 5 2 | + | 19 10 | ) | x | × | 1 2 | − | 1 2 | x |
| = | 22 5 | − | 5 2 | x | × | 1 2 | − | 19 10 | x | × | 1 2 | − | 1 2 | x |
| = | 22 5 | − | 5 4 | x | − | 19 20 | x | − | 1 2 | x |
| = | 22 5 | − | 27 10 | x |
22 5 | − | 27 10 | x | = | 6 5 |
| - | 27 10 | x | = | 6 5 | − | 22 5 |
| - | 27 10 | x | = | - | 16 5 |
16 5 | = | 27 10 | x |
27 10 | x | = | 16 5 |
| x | = | 16 5 | ÷ | 27 10 |
| = | 16 5 | × | 10 27 |
| = | 16 | × | 2 27 |
| x | = | 32 27 |
