| 方程左边 = | 3 | ÷ | 4 | × | x | + | 6 | + | ( | 4 | ÷ | 3 | ) | x | − | ( | 25 | ÷ | 6 | ) |
| = | 3 4 | x | + | 6 | + | ( | 4 | ÷ | 3 | ) | x | − | ( | 25 | ÷ | 6 | ) |
| = | 3 4 | x | + | 6 | + | 4 | ÷ | 3 | × | x | − | ( | 25 | ÷ | 6 | ) |
| = | 3 4 | x | + | 6 | + | 4 3 | x | − | ( | 25 | ÷ | 6 | ) |
| = | 25 12 | x | + | 6 | − | ( | 25 | ÷ | 6 | ) |
| = | 25 12 | x | + | 6 | − | 25 | ÷ | 6 |
| = | 25 12 | x | + | 6 | − | 25 6 |
| = | 25 12 | x | + | 11 6 |
25 12 | x | + | 11 6 | = | 0 |
25 12 | x | = | 0 | − | 11 6 |
25 12 | x | = | - | 11 6 |
| x | = | - | 11 6 | ÷ | 25 12 |
| = | - | 11 6 | × | 12 25 |
| = | - | 11 | × | 2 25 |
