x | × | 1 | ÷ | x | − | x | × | 5000 | + | 5 | ( | 1 | ÷ | x | − | 5000 | ) | = | 300000 |
1 | × | 1 | ÷ | 1 | − | 5000 | x | + | 5 | × | 1 | ÷ | x | − | 5 | × | 5000 | = | 300000 |
1 | − | 5000 | x | + | 5 | ÷ | x | − | 25000 | = | 300000 |
- | 24999 | − | 5000 | x | + | 5 | ÷ | x | = | 300000 |
方程两边同时乘以: | x |
- | 24999 | x | − | 5000 | x | x | + | 5 | = | 300000 | x |
