79 5 | x | + | 121 5 | ( | 110 | − | x | ) | = | 11084 5 |
| 方程左边 = | 79 5 | x | + | 121 5 | × | 110 | − | 121 5 | x |
| = | 79 5 | x | + | 2662 | − | 121 5 | x |
| = | - | 42 5 | x | + | 2662 |
| - | 42 5 | x | + | 2662 | = | 11084 5 |
| - | 42 5 | x | = | 11084 5 | − | 2662 |
| - | 42 5 | x | = | - | 2226 5 |
2226 5 | = | 42 5 | x |
42 5 | x | = | 2226 5 |
| x | = | 2226 5 | ÷ | 42 5 |
| = | 2226 5 | × | 5 42 |
| = | 53 | × | 1 |
| x | = | 53 |
