| 方程左边 = | ( | 1 | ÷ | 4 | ) | x | + | ( | 1 | ÷ | 6 | ) | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 1 | ÷ | 4 | × | x | + | ( | 1 | ÷ | 6 | ) | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 1 4 | x | + | ( | 1 | ÷ | 6 | ) | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 1 4 | x | + | 1 | ÷ | 6 | × | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 1 4 | x | + | 1 6 | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 5 12 | x | − | ( | 1 | ÷ | 4 | ) | x |
| = | 5 12 | x | − | 1 | ÷ | 4 | × | x |
| = | 5 12 | x | − | 1 4 | x |
| = | 1 6 | x |
1 6 | x | = | 1 |
| x | = | 1 | ÷ | 1 6 |
| = | 1 | × | 6 |
| x | = | 6 |
