| ( | ( | 2 | x | + | 6 | ) | ÷ | 5 | ) | = | ( | 3 | ÷ | 2 | ) | x | − | ( | ( | 2 | x | − | 14 | ) | ÷ | 3 | ) |
| 方程左边 = | ( | 2 | x | + | 6 | ) | ÷ | 5 |
| = | 2 | x | × | 1 5 | + | 6 | × | 1 5 |
| = | 2 5 | x | + | 6 5 |
2 5 | x | + | 6 5 | = | ( | 3 | ÷ | 2 | ) | x | − | ( | ( | 2 | x | − | 14 | ) | ÷ | 3 | ) |
| 方程右边 = | 3 | ÷ | 2 | × | x | − | ( | ( | 2 | x | − | 14 | ) | ÷ | 3 | ) |
| = | 3 2 | x | − | ( | ( | 2 | x | − | 14 | ) | ÷ | 3 | ) |
| = | 3 2 | x | − | ( | 2 | x | − | 14 | ) | ÷ | 3 |
| = | 3 2 | x | − | 2 | x | × | 1 3 | + | 14 | × | 1 3 |
| = | 3 2 | x | − | 2 3 | x | + | 14 3 |
| = | 5 6 | x | + | 14 3 |
2 5 | x | + | 6 5 | = | 5 6 | x | + | 14 3 |
2 5 | x | − | 5 6 | x | = | 14 3 | − | 6 5 |
| - | 13 30 | x | = | 14 3 | − | 6 5 |
| - | 13 30 | x | = | 52 15 |
| - | 52 15 | = | 13 30 | x |
13 30 | x | = | - | 52 15 |
| x | = | - | 52 15 | ÷ | 13 30 |
| = | - | 52 15 | × | 30 13 |
| = | - | 4 | × | 2 |
| x | = | - | 8 |
