方程左边 = | 807 100 | + | X | × | 257 10000 |
807 100 | + | 257 10000 | X | = | X |
257 10000 | X | − | X | = | - | 807 100 |
- | 9743 10000 | X | = | - | 807 100 |
807 100 | = | 9743 10000 | X |
9743 10000 | X | = | 807 100 |
X | = | 807 100 | ÷ | 9743 10000 |
= | 807 100 | × | 10000 9743 |
= | 807 | × | 100 9743 |
