x | ÷ | ( | 1 10 | + | x | ) | = | 849 500 |
方程两边同时乘以: | ( | 1 10 | + | x | ) |
x | = | 849 500 | ( | 1 10 | + | x | ) |
x | = | 849 500 | × | 1 10 | + | 849 500 | x |
x | = | 849 5000 | + | 849 500 | x |
x | − | 849 500 | x | = | 849 5000 |
- | 349 500 | x | = | 849 5000 |
- | 849 5000 | = | 349 500 | x |
349 500 | x | = | - | 849 5000 |
x | = | - | 849 5000 | ÷ | 349 500 |
= | - | 849 5000 | × | 500 349 |
= | - | 849 10 | × | 1 349 |
x | = | - | 849 3490 |
x | = | - 0.243266 |
