| 方程左边 = | 24 | × | 1 3 | + | x | × | 1 3 | − | ( | 4 | x | + | 8 | ) | × | 1 3 |
| = | 8 | + | x | × | 1 3 | − | ( | 4 | x | + | 8 | ) | × | 1 3 |
| = | 8 | + | 1 3 | x | − | 4 | x | × | 1 3 | − | 8 | × | 1 3 |
| = | 8 | + | 1 3 | x | − | 4 3 | x | − | 8 3 |
| = | 16 3 | − | 1 | x |
16 3 | − | 1 | x | = | 5 |
| - | 1 | x | = | 5 | − | 16 3 |
| - | x | = | 5 | − | 16 3 |
| - | x | = | - | 1 3 |
