617 1000 | ( | 5 | − | 1 10 | x | ) | = | 1 10 | x |
| 方程左边 = | 617 1000 | × | 5 | − | 617 1000 | × | 1 10 | x |
| = | 617 200 | − | 617 10000 | x |
617 200 | − | 617 10000 | x | = | 1 10 | x |
| - | 617 10000 | x | − | 1 10 | x | = | - | 617 200 |
| - | 1617 10000 | x | = | - | 617 200 |
617 200 | = | 1617 10000 | x |
1617 10000 | x | = | 617 200 |
| x | = | 617 200 | ÷ | 1617 10000 |
| = | 617 200 | × | 10000 1617 |
| = | 617 | × | 50 1617 |
| x | = | 30850 1617 |
