x | ÷ | ( | 100 | + | x | ) | = | 1569 10000 |
方程两边同时乘以: | ( | 100 | + | x | ) |
x | = | 1569 10000 | ( | 100 | + | x | ) |
x | = | 1569 10000 | × | 100 | + | 1569 10000 | x |
x | = | 1569 100 | + | 1569 10000 | x |
x | − | 1569 10000 | x | = | 1569 100 |
8431 10000 | x | = | 1569 100 |
x | = | 1569 100 | ÷ | 8431 10000 |
= | 1569 100 | × | 10000 8431 |
= | 1569 | × | 100 8431 |
x | = | 156900 8431 |
x | = | 18.609892 |
