2430 | ÷ | ( | x | + | 6 | ) | = | 7200 | ÷ | x |
方程两边同时乘以: | ( | x | + | 6 | ) | , | x |
2430 | x | = | 7200 | ( | x | + | 6 | ) |
2430 | x | = | 7200 | x | + | 7200 | × | 6 |
2430 | x | = | 7200 | x | + | 43200 |
2430 | x | − | 7200 | x | = | 43200 |
- | 4770 | x | = | 43200 |
- | 43200 | = | 4770 | x |
4770 | x | = | - | 43200 |
x | = | - | 43200 | ÷ | 4770 |
= | - | 43200 | × | 1 4770 |
= | - | 480 | × | 1 53 |
x | = | - | 480 53 |
