1847 50 | ( | 1 | − | x | ) | = | 457 50 |
方程左边 = | 1847 50 | × | 1 | − | 1847 50 | x |
= | 1847 50 | − | 1847 50 | x |
1847 50 | − | 1847 50 | x | = | 457 50 |
- | 1847 50 | x | = | 457 50 | − | 1847 50 |
- | 1847 50 | x | = | - | 139 5 |
139 5 | = | 1847 50 | x |
1847 50 | x | = | 139 5 |
x | = | 139 5 | ÷ | 1847 50 |
= | 139 5 | × | 50 1847 |
= | 139 | × | 10 1847 |
x | = | 1390 1847 |
