| 方程右边 = | - | 3 | x | − | 3 | × | 12 | − | 16 |
| = | - | 3 | x | − | 36 | − | 16 |
| = | - | 3 | x | − | 52 |
| 192 | x | + | 3653 | = | - | 3 | x | − | 52 |
| 192 | x | + | 3 | x | = | - | 52 | − | 3653 |
| 195 | x | = | - | 52 | − | 3653 |
| 195 | x | = | - | 3705 |
| x | = | - | 3705 | ÷ | 195 |
| = | - | 3705 | × | 1 195 |
| = | - | 19 | × | 1 |
