x | ÷ | ( | 1 10 | − | x | ) | = | 11 2000 |
方程两边同时乘以: | ( | 1 10 | − | x | ) |
x | = | 11 2000 | ( | 1 10 | − | x | ) |
x | = | 11 2000 | × | 1 10 | − | 11 2000 | x |
x | = | 11 20000 | − | 11 2000 | x |
x | + | 11 2000 | x | = | 11 20000 |
2011 2000 | x | = | 11 20000 |
x | = | 11 20000 | ÷ | 2011 2000 |
= | 11 20000 | × | 2000 2011 |
= | 11 10 | × | 1 2011 |
x | = | 11 20110 |
x | = | 0.000547 |
