X | ÷ | ( | X | + | 13889 25 | ) | = | 1 100 |
方程两边同时乘以: | ( | X | + | 13889 25 | ) |
X | = | 1 100 | ( | X | + | 13889 25 | ) |
X | = | 1 100 | X | + | 1 100 | × | 13889 25 |
X | = | 1 100 | X | + | 13889 2500 |
X | − | 1 100 | X | = | 13889 2500 |
99 100 | X | = | 13889 2500 |
X | = | 13889 2500 | ÷ | 99 100 |
= | 13889 2500 | × | 100 99 |
= | 13889 25 | × | 1 99 |
X | = | 13889 2475 |
X | = | 5.611717 |
