| ( | x | − | 17 100 | ) | ÷ | ( | 9 50 | − | x | ) | = | 11 5 |
| 方程两边同时乘以: | ( | 9 50 | − | x | ) |
| ( | x | − | 17 100 | ) | = | 11 5 | ( | 9 50 | − | x | ) |
| x | − | 17 100 | = | 11 5 | ( | 9 50 | − | x | ) |
| x | − | 17 100 | = | 11 5 | × | 9 50 | − | 11 5 | x |
| x | − | 17 100 | = | 99 250 | − | 11 5 | x |
| x | + | 11 5 | x | = | 99 250 | + | 17 100 |
16 5 | x | = | 99 250 | + | 17 100 |
16 5 | x | = | 283 500 |
| x | = | 283 500 | ÷ | 16 5 |
| = | 283 500 | × | 5 16 |
| = | 283 100 | × | 1 16 |
| x | = | 283 1600 |
| x | = | 0.176875 |
