| x | ÷ | ( | x | + | 11 | ) | = | 1697 2000 |
| 方程两边同时乘以: | ( | x | + | 11 | ) |
| x | = | 1697 2000 | ( | x | + | 11 | ) |
| x | = | 1697 2000 | x | + | 1697 2000 | × | 11 |
| x | = | 1697 2000 | x | + | 18667 2000 |
| x | − | 1697 2000 | x | = | 18667 2000 |
303 2000 | x | = | 18667 2000 |
| x | = | 18667 2000 | ÷ | 303 2000 |
| = | 18667 2000 | × | 2000 303 |
| = | 18667 | × | 1 303 |
| x | = | 18667 303 |
| x | = | 61.607261 |
