| ( | x | + | 1 | ) | = | 50 | ( | x | − | 1 | ) | − | 10 |
| 方程左边 = | x | + | 1 |
| x | + | 1 | = | 50 | ( | x | − | 1 | ) | − | 10 |
| 方程右边 = | 50 | x | − | 50 | × | 1 | − | 10 |
| = | 50 | x | − | 50 | − | 10 |
| = | 50 | x | − | 60 |
| x | + | 1 | = | 50 | x | − | 60 |
| x | − | 50 | x | = | - | 60 | − | 1 |
| - | 49 | x | = | - | 60 | − | 1 |
| - | 49 | x | = | - | 61 |
| 61 | = | 49 | x |
| 49 | x | = | 61 |
| x | = | 61 | ÷ | 49 |
| = | 61 | × | 1 49 |
| x | = | 61 49 |
| x | = | 1.244898 |
