1 50 | x | ÷ | 3 100 | + | 1 | = | - | 9 50 | x | + | 9 50 | − | 3 2 | − | 3 | x | ÷ | 2 |
| 方程左边 = | 2 3 | x | + | 1 |
2 3 | x | + | 1 | = | - | 9 50 | x | + | 9 50 | − | 3 2 | − | 3 | x | ÷ | 2 |
| 方程右边 = | - | 9 50 | x | + | 9 50 | − | 3 2 | − | 3 2 | x |
| = | - | 42 25 | x | − | 33 25 |
2 3 | x | + | 1 | = | - | 42 25 | x | − | 33 25 |
2 3 | x | + | 42 25 | x | = | - | 33 25 | − | 1 |
176 75 | x | = | - | 33 25 | − | 1 |
176 75 | x | = | - | 58 25 |
| x | = | - | 58 25 | ÷ | 176 75 |
| = | - | 58 25 | × | 75 176 |
| = | - | 29 | × | 3 88 |
| x | = | - | 87 88 |
| x | = | - 0.988636 |
