| 方程左边 = | 4 | − | 6 | x | + | 6 | × | 3 |
| = | 4 | − | 6 | x | + | 18 |
| = | 22 | − | 6 | x |
| 22 | − | 6 | x | = | 10 | ÷ | 3 | × | x | − | 6 | ( | x | − | 7 | ) | × | 10 |
| 方程右边 = | 10 3 | x | − | 60 | ( | x | − | 7 | ) |
| 22 | − | 6 | x | = | 10 3 | x | − | 60 | ( | x | − | 7 | ) |
| 方程右边 = | 10 3 | x | − | 60 | x | + | 60 | × | 7 |
| = | 10 3 | x | − | 60 | x | + | 420 |
| = | - | 170 3 | x | + | 420 |
| 22 | − | 6 | x | = | - | 170 3 | x | + | 420 |
| - | 6 | x | + | 170 3 | x | = | 420 | − | 22 |
152 3 | x | = | 420 | − | 22 |
152 3 | x | = | 398 |
| x | = | 398 | ÷ | 152 3 |
