| 2 | ( | 7 | x | ÷ | 4 | ) | ÷ | 3 | = | 63 | − | x | + | 35 | ÷ | 6 |
| 方程左边 = | 2 3 | ( | 7 | x | ÷ | 4 | ) |
2 3 | ( | 7 | x | ÷ | 4 | ) | = | 63 | − | x | + | 35 | ÷ | 6 |
| 方程左边 = | 2 3 | × | 7 | x | ÷ | 4 |
| = | 7 6 | x |
7 6 | x | = | 63 | − | x | + | 35 | ÷ | 6 |
| 方程右边 = | 63 | − | x | + | 35 6 |
| = | 413 6 | − | x |
7 6 | x | = | 413 6 | − | x |
7 6 | x | + | x | = | 413 6 |
13 6 | x | = | 413 6 |
| x | = | 413 6 | ÷ | 13 6 |
| = | 413 6 | × | 6 13 |
| = | 413 | × | 1 13 |
| x | = | 413 13 |
