x | ÷ | ( | x | + | 2 | ) | = | 97 10000 |
方程两边同时乘以: | ( | x | + | 2 | ) |
x | = | 97 10000 | ( | x | + | 2 | ) |
x | = | 97 10000 | x | + | 97 10000 | × | 2 |
x | = | 97 10000 | x | + | 97 5000 |
x | − | 97 10000 | x | = | 97 5000 |
9903 10000 | x | = | 97 5000 |
x | = | 97 5000 | ÷ | 9903 10000 |
= | 97 5000 | × | 10000 9903 |
= | 97 | × | 2 9903 |
x | = | 194 9903 |
x | = | 0.01959 |
