| x | − | ( | x | − | 3 | ) | ÷ | 3 | = | 2 | ( | 5 | ÷ | 3 | − | x | ) |
| 方程左边 = | x | − | x | × | 1 3 | + | 3 | × | 1 3 |
| = | x | − | x | × | 1 3 | + | 1 |
| = | 2 3 | x | + | 1 |
2 3 | x | + | 1 | = | 2 | ( | 5 | ÷ | 3 | − | x | ) |
| 方程右边 = | 2 | × | 5 | ÷ | 3 | − | 2 | x |
| = | 10 3 | − | 2 | x |
2 3 | x | + | 1 | = | 10 3 | − | 2 | x |
2 3 | x | + | 2 | x | = | 10 3 | − | 1 |
8 3 | x | = | 10 3 | − | 1 |
8 3 | x | = | 7 3 |
| x | = | 7 3 | ÷ | 8 3 |
| = | 7 3 | × | 3 8 |
| = | 7 | × | 1 8 |
| x | = | 7 8 |
| x | = | 0.875 |
