| ( | 1 | ÷ | 5 | ) | ( | 25 | x | + | 250 | ) | − | 6 | x | = | ( | 1 | ÷ | 6 | ) | x | + | 8 |
| 方程左边 = | 1 | ÷ | 5 | × | ( | 25 | x | + | 250 | ) | − | 6 | x |
| = | 1 5 | ( | 25 | x | + | 250 | ) | − | 6 | x |
| = | 1 5 | × | 25 | x | + | 1 5 | × | 250 | − | 6 | x |
| = | 5 | x | + | 50 | − | 6 | x |
| = | - | 1 | x | + | 50 |
| - | 1 | x | + | 50 | = | ( | 1 | ÷ | 6 | ) | x | + | 8 |
| 方程右边 = | 1 | ÷ | 6 | × | x | + | 8 |
| = | 1 6 | x | + | 8 |
| - | 1 | x | + | 50 | = | 1 6 | x | + | 8 |
| - | 1 | x | − | 1 6 | x | = | 8 | − | 50 |
| - | 7 6 | x | = | 8 | − | 50 |
| - | 7 6 | x | = | - | 42 |
| 42 | = | 7 6 | x |
7 6 | x | = | 42 |
| x | = | 42 | ÷ | 7 6 |
| = | 42 | × | 6 7 |
| = | 6 | × | 6 |
| x | = | 36 |
