291 2000 | x | ÷ | ( | 1 | − | 291 2000 | x | ) | = | 1 10 |
| 方程两边同时乘以: | ( | 1 | − | 291 2000 | x | ) |
291 2000 | x | = | 1 10 | ( | 1 | − | 291 2000 | x | ) |
291 2000 | x | = | 1 10 | × | 1 | − | 1 10 | × | 291 2000 | x |
291 2000 | x | = | 1 10 | − | 291 20000 | x |
291 2000 | x | + | 291 20000 | x | = | 1 10 |
3201 20000 | x | = | 1 10 |
| x | = | 1 10 | ÷ | 3201 20000 |
| = | 1 10 | × | 20000 3201 |
| = | 1 | × | 2000 3201 |
| x | = | 2000 3201 |
| x | = | 0.624805 |
