| 6 | − | 3 | ( | x | + | 333 1000 | ) | = | 333 500 |
| 方程左边 = | 6 | − | 3 | x | − | 3 | × | 333 1000 |
| = | 6 | − | 3 | x | − | 999 1000 |
| = | 5001 1000 | − | 3 | x |
5001 1000 | − | 3 | x | = | 333 500 |
| - | 3 | x | = | 333 500 | − | 5001 1000 |
| - | 3 | x | = | - | 867 200 |
867 200 | = | 3 | x |
| 3 | x | = | 867 200 |
| x | = | 867 200 | ÷ | 3 |
| = | 867 200 | × | 1 3 |
| = | 289 200 | × | 1 |
| x | = | 289 200 |
| x | = | 1.445 |
