x | ÷ | ( | x | + | 2 | ) | = | 721 10000 |
方程两边同时乘以: | ( | x | + | 2 | ) |
x | = | 721 10000 | ( | x | + | 2 | ) |
x | = | 721 10000 | x | + | 721 10000 | × | 2 |
x | = | 721 10000 | x | + | 721 5000 |
x | − | 721 10000 | x | = | 721 5000 |
9279 10000 | x | = | 721 5000 |
x | = | 721 5000 | ÷ | 9279 10000 |
= | 721 5000 | × | 10000 9279 |
= | 721 | × | 2 9279 |
x | = | 1442 9279 |
x | = | 0.155405 |
