| ( | x | − | 43 200 | ) | ÷ | ( | 3 2 | − | x | ) | = | 19 10 | ÷ | 7 5 |
| 方程两边同时乘以: | ( | 3 2 | − | x | ) |
| ( | x | − | 43 200 | ) | = | 19 10 | ÷ | 7 5 | × | ( | 3 2 | − | x | ) |
| x | − | 43 200 | = | 19 10 | ÷ | 7 5 | × | ( | 3 2 | − | x | ) |
| x | − | 43 200 | = | 19 10 | ÷ | 7 5 | × | 3 2 | − | 19 10 | ÷ | 7 5 | × | x |
| x | − | 43 200 | = | 57 28 | − | 19 14 | x |
| x | + | 19 14 | x | = | 57 28 | + | 43 200 |
33 14 | x | = | 57 28 | + | 43 200 |
33 14 | x | = | 3151 1400 |
| x | = | 3151 1400 | ÷ | 33 14 |
| = | 3151 1400 | × | 14 33 |
| = | 3151 100 | × | 1 33 |
| x | = | 3151 3300 |
| x | = | 0.954848 |
