| ( | x | − | 43 200 | ) | ÷ | ( | 3 2 | − | x | ) | = | 7 5 | ÷ | 19 10 |
| 方程两边同时乘以: | ( | 3 2 | − | x | ) |
| ( | x | − | 43 200 | ) | = | 7 5 | ÷ | 19 10 | × | ( | 3 2 | − | x | ) |
| x | − | 43 200 | = | 7 5 | ÷ | 19 10 | × | ( | 3 2 | − | x | ) |
| x | − | 43 200 | = | 7 5 | ÷ | 19 10 | × | 3 2 | − | 7 5 | ÷ | 19 10 | × | x |
| x | − | 43 200 | = | 21 19 | − | 14 19 | x |
| x | + | 14 19 | x | = | 21 19 | + | 43 200 |
33 19 | x | = | 21 19 | + | 43 200 |
33 19 | x | = | 5017 3800 |
| x | = | 5017 3800 | ÷ | 33 19 |
| = | 5017 3800 | × | 19 33 |
| = | 5017 200 | × | 1 33 |
| x | = | 5017 6600 |
| x | = | 0.760152 |
