| 方程右边 = | - | 9 50 | x | × | 25 3 | + | 9 50 | × | 25 3 | − | ( | 3 2 | − | 3 | x | ) | × | 1 2 |
| = | - | 3 2 | x | + | 3 2 | − | ( | 3 2 | − | 3 | x | ) | × | 1 2 |
| = | - | 3 2 | x | + | 3 2 | − | 3 2 | × | 1 2 | + | 3 | x | × | 1 2 |
| = | - | 3 2 | x | + | 3 2 | − | 3 4 | + | 3 2 | x |
| = | - | 0 | x | + | 3 4 |
2 3 | x | + | 1 | = | - | 0 | x | + | 3 4 |
2 3 | x | = | 3 4 | − | 1 |
2 3 | x | = | - | 1 4 |
| x | = | - | 1 4 | ÷ | 2 3 |
| = | - | 1 4 | × | 3 2 |
| x | = | - | 3 8 |
