| - | ( | 4 | ÷ | 3 | ) | x | + | ( | 25 | ÷ | 6 | ) | = | ( | 24 | ÷ | 7 | ) | x |
| 方程左边 = | - | 4 | ÷ | 3 | × | x | + | ( | 25 | ÷ | 6 | ) |
| = | - | 4 3 | x | + | ( | 25 | ÷ | 6 | ) |
| = | - | 4 3 | x | + | 25 | ÷ | 6 |
| = | - | 4 3 | x | + | 25 6 |
| - | 4 3 | x | + | 25 6 | = | ( | 24 | ÷ | 7 | ) | x |
| 方程右边 = | 24 | ÷ | 7 | × | x |
| = | 24 7 | x |
| - | 4 3 | x | + | 25 6 | = | 24 7 | x |
| - | 4 3 | x | − | 24 7 | x | = | - | 25 6 |
| - | 100 21 | x | = | - | 25 6 |
25 6 | = | 100 21 | x |
100 21 | x | = | 25 6 |
| x | = | 25 6 | ÷ | 100 21 |
| = | 25 6 | × | 21 100 |
| = | 1 2 | × | 7 4 |
| x | = | 7 8 |
| x | = | 0.875 |
