| x | + | 2 | ( | x | − | 3 | ) | ÷ | 3 | = | 6 | − | x | − | 7 | ÷ | 6 |
| 方程左边 = | x | + | 2 3 | ( | x | − | 3 | ) |
| x | + | 2 3 | ( | x | − | 3 | ) | = | 6 | − | x | − | 7 | ÷ | 6 |
| 方程左边 = | x | + | 2 3 | x | − | 2 3 | × | 3 |
| = | x | + | 2 3 | x | − | 2 |
| = | 5 3 | x | − | 2 |
5 3 | x | − | 2 | = | 6 | − | x | − | 7 | ÷ | 6 |
| 方程右边 = | 6 | − | x | − | 7 6 |
| = | 29 6 | − | x |
5 3 | x | − | 2 | = | 29 6 | − | x |
5 3 | x | + | x | = | 29 6 | + | 2 |
8 3 | x | = | 29 6 | + | 2 |
8 3 | x | = | 41 6 |
| x | = | 41 6 | ÷ | 8 3 |
| = | 41 6 | × | 3 8 |
| = | 41 2 | × | 1 8 |
| x | = | 41 16 |
| x | = | 2.5625 |
