( | 1000 | + | x | ) | ÷ | ( | 1000 | ÷ | 223 100 | + | x | ) | = | 8 5 |
方程两边同时乘以: | ( | 1000 | ÷ | 223 100 | + | x | ) |
( | 1000 | + | x | ) | = | 8 5 | ( | 1000 | ÷ | 223 100 | + | x | ) |
1000 | + | x | = | 8 5 | ( | 1000 | ÷ | 223 100 | + | x | ) |
1000 | + | x | = | 8 5 | × | 1000 | ÷ | 223 100 | + | 8 5 | x |
1000 | + | x | = | 160000 223 | + | 8 5 | x |
x | − | 8 5 | x | = | 160000 223 | − | 1000 |
- | 3 5 | x | = | 160000 223 | − | 1000 |
- | 3 5 | x | = | - | 63000 223 |
63000 223 | = | 3 5 | x |
3 5 | x | = | 63000 223 |
x | = | 63000 223 | ÷ | 3 5 |
= | 63000 223 | × | 5 3 |
= | 21000 223 | × | 5 |
x | = | 105000 223 |
