36 5 | x | ÷ | 6 | = | ( | 36 5 | x | − | 18 | ) | ÷ | 4 |
| 方程左边 = | 6 5 | x |
6 5 | x | = | ( | 36 5 | x | − | 18 | ) | ÷ | 4 |
| 方程右边 = | 36 5 | x | × | 1 4 | − | 18 | × | 1 4 |
| = | 9 5 | x | − | 9 2 |
6 5 | x | = | 9 5 | x | − | 9 2 |
6 5 | x | − | 9 5 | x | = | - | 9 2 |
| - | 3 5 | x | = | - | 9 2 |
9 2 | = | 3 5 | x |
3 5 | x | = | 9 2 |
| x | = | 9 2 | ÷ | 3 5 |
| = | 9 2 | × | 5 3 |
| = | 3 2 | × | 5 |
| x | = | 15 2 |
| x | = | 7.5 |
