| ( | 1008 | + | x | ) | ÷ | ( | 2176 | − | x | ) | = | 23 20 |
| 方程两边同时乘以: | ( | 2176 | − | x | ) |
| ( | 1008 | + | x | ) | = | 23 20 | ( | 2176 | − | x | ) |
| 1008 | + | x | = | 23 20 | ( | 2176 | − | x | ) |
| 1008 | + | x | = | 23 20 | × | 2176 | − | 23 20 | x |
| 1008 | + | x | = | 12512 5 | − | 23 20 | x |
| x | + | 23 20 | x | = | 12512 5 | − | 1008 |
43 20 | x | = | 12512 5 | − | 1008 |
43 20 | x | = | 7472 5 |
| x | = | 7472 5 | ÷ | 43 20 |
| = | 7472 5 | × | 20 43 |
| = | 7472 | × | 4 43 |
| x | = | 29888 43 |
