2 | x | ÷ | ( | 1 | + | x | ) | = | 28571 100000 |
方程两边同时乘以: | ( | 1 | + | x | ) |
2 | x | = | 28571 100000 | ( | 1 | + | x | ) |
2 | x | = | 28571 100000 | × | 1 | + | 28571 100000 | x |
2 | x | = | 28571 100000 | + | 28571 100000 | x |
2 | x | − | 28571 100000 | x | = | 28571 100000 |
171429 100000 | x | = | 28571 100000 |
x | = | 28571 100000 | ÷ | 171429 100000 |
= | 28571 100000 | × | 100000 171429 |
= | 28571 | × | 1 171429 |
x | = | 28571 171429 |
