26 5 | x | + | 38 5 | ( | 14 | − | x | ) | = | 436 5 |
| 方程左边 = | 26 5 | x | + | 38 5 | × | 14 | − | 38 5 | x |
| = | 26 5 | x | + | 532 5 | − | 38 5 | x |
| = | - | 12 5 | x | + | 532 5 |
| - | 12 5 | x | + | 532 5 | = | 436 5 |
| - | 12 5 | x | = | 436 5 | − | 532 5 |
| - | 12 5 | x | = | - | 96 5 |
96 5 | = | 12 5 | x |
12 5 | x | = | 96 5 |
| x | = | 96 5 | ÷ | 12 5 |
| = | 96 5 | × | 5 12 |
| = | 8 | × | 1 |
| x | = | 8 |
