43 625 | x | ÷ | ( | x | + | 17 25 | ) | = | 17 250 |
| 方程两边同时乘以: | ( | x | + | 17 25 | ) |
43 625 | x | = | 17 250 | ( | x | + | 17 25 | ) |
43 625 | x | = | 17 250 | x | + | 17 250 | × | 17 25 |
43 625 | x | = | 17 250 | x | + | 289 6250 |
43 625 | x | − | 17 250 | x | = | 289 6250 |
1 1250 | x | = | 289 6250 |
| x | = | 289 6250 | ÷ | 1 1250 |
| = | 289 6250 | × | 1250 |
| = | 289 5 | × | 1 |
| x | = | 289 5 |
| x | = | 57.8 |
