( | 713 100 | − | x | ) | ÷ | x | = | 157 10 |
方程两边同时乘以: | x |
( | 713 100 | − | x | ) | = | 157 10 | x |
713 100 | − | x | = | 157 10 | x |
- | x | − | 157 10 | x | = | - | 713 100 |
- | 167 10 | x | = | - | 713 100 |
713 100 | = | 167 10 | x |
167 10 | x | = | 713 100 |
x | = | 713 100 | ÷ | 167 10 |
= | 713 100 | × | 10 167 |
= | 713 10 | × | 1 167 |
x | = | 713 1670 |
x | = | 0.426946 |
