167 20 | x | ÷ | ( | 1 | − | 167 20 | x | ) | = | 3 10 |
| 方程两边同时乘以: | ( | 1 | − | 167 20 | x | ) |
167 20 | x | = | 3 10 | ( | 1 | − | 167 20 | x | ) |
167 20 | x | = | 3 10 | × | 1 | − | 3 10 | × | 167 20 | x |
167 20 | x | = | 3 10 | − | 501 200 | x |
167 20 | x | + | 501 200 | x | = | 3 10 |
2171 200 | x | = | 3 10 |
| x | = | 3 10 | ÷ | 2171 200 |
| = | 3 10 | × | 200 2171 |
| = | 3 | × | 20 2171 |
| x | = | 60 2171 |
| x | = | 0.027637 |
