| 83 | x | + | 95 | ( | 60 | − | x | ) | = | 60 | × | 92 |
| 方程左边 = | 83 | x | + | 95 | × | 60 | − | 95 | x |
| = | 83 | x | + | 5700 | − | 95 | x |
| = | - | 12 | x | + | 5700 |
| - | 12 | x | + | 5700 | = | 60 | × | 92 |
| 方程右边 = | 5520 |
| - | 12 | x | + | 5700 | = | 5520 |
| - | 12 | x | = | 5520 | − | 5700 |
| - | 12 | x | = | - | 180 |
| 180 | = | 12 | x |
| 12 | x | = | 180 |
| x | = | 180 | ÷ | 12 |
| = | 180 | × | 1 12 |
| = | 15 | × | 1 |
| x | = | 15 |
