( | 189 2 | − | X | ) | ÷ | 1000 | − | X | ÷ | 126 | = | 333 1000 |
方程左边 = | 189 2 | × | 1 1000 | − | X | × | 1 1000 | − | 1 126 | X |
= | 189 2000 | − | X | × | 1 1000 | − | 1 126 | X |
= | 189 2000 | − | 563 63000 | X |
189 2000 | − | 563 63000 | X | = | 333 1000 |
- | 563 63000 | X | = | 333 1000 | − | 189 2000 |
- | 563 63000 | X | = | 477 2000 |
- | 477 2000 | = | 563 63000 | X |
563 63000 | X | = | - | 477 2000 |
X | = | - | 477 2000 | ÷ | 563 63000 |
= | - | 477 2000 | × | 63000 563 |
= | - | 477 2 | × | 63 563 |
