| 1 | ÷ | 4 | × | x | − | 1 | ÷ | 4 | = | 1 | ÷ | 3 | × | x | − | 46 | ÷ | 30 |
| 方程左边 = | 1 4 | x | − | 1 4 |
1 4 | x | − | 1 4 | = | 1 | ÷ | 3 | × | x | − | 46 | ÷ | 30 |
| 方程右边 = | 1 3 | x | − | 23 15 |
1 4 | x | − | 1 4 | = | 1 3 | x | − | 23 15 |
1 4 | x | − | 1 3 | x | = | - | 23 15 | + | 1 4 |
| - | 1 12 | x | = | - | 23 15 | + | 1 4 |
| - | 1 12 | x | = | - | 77 60 |
77 60 | = | 1 12 | x |
1 12 | x | = | 77 60 |
| x | = | 77 60 | ÷ | 1 12 |
| = | 77 60 | × | 12 |
| = | 77 5 | × | 1 |
| x | = | 77 5 |
| x | = | 15.4 |
