2 25 | ÷ | 4 | = | ( | 3 25 | ÷ | 4 | ) | + | ( | ( | x | − | 6 5 | ) | ÷ | 6 5 | ) |
| 方程左边 = | 1 50 |
1 50 | = | ( | 3 25 | ÷ | 4 | ) | + | ( | ( | x | − | 6 5 | ) | ÷ | 6 5 | ) |
| 方程右边 = | 3 25 | ÷ | 4 | + | ( | ( | x | − | 6 5 | ) | ÷ | 6 5 | ) |
| = | 3 100 | + | ( | ( | x | − | 6 5 | ) | ÷ | 6 5 | ) |
| = | 3 100 | + | ( | x | − | 6 5 | ) | ÷ | 6 5 |
| = | 3 100 | + | x | × | 5 6 | − | 6 5 | × | 5 6 |
| = | 3 100 | + | x | × | 5 6 | − | 1 |
| = | - | 97 100 | + | 5 6 | x |
1 50 | = | - | 97 100 | + | 5 6 | x |
| - | 5 6 | x | = | - | 97 100 | − | 1 50 |
| - | 5 6 | x | = | - | 99 100 |
99 100 | = | 5 6 | x |
5 6 | x | = | 99 100 |
| x | = | 99 100 | ÷ | 5 6 |
| = | 99 100 | × | 6 5 |
| = | 99 50 | × | 3 5 |
| x | = | 297 250 |
| x | = | 1.188 |
