| x | ÷ | ( | x | + | 2369 100 | ) | = | 3 100 |
| 方程两边同时乘以: | ( | x | + | 2369 100 | ) |
| x | = | 3 100 | ( | x | + | 2369 100 | ) |
| x | = | 3 100 | x | + | 3 100 | × | 2369 100 |
| x | = | 3 100 | x | + | 7107 10000 |
| x | − | 3 100 | x | = | 7107 10000 |
97 100 | x | = | 7107 10000 |
| x | = | 7107 10000 | ÷ | 97 100 |
| = | 7107 10000 | × | 100 97 |
| = | 7107 100 | × | 1 97 |
| x | = | 7107 9700 |
| x | = | 0.73268 |
