| ( | 4 | x | + | 8 | ) | ÷ | ( | 3 | x | + | 24 | ) | = | 5 | ÷ | 6 |
| 方程两边同时乘以: | ( | 3 | x | + | 24 | ) |
| ( | 4 | x | + | 8 | ) | = | 5 | ÷ | 6 | × | ( | 3 | x | + | 24 | ) |
| 4 | x | + | 8 | = | 5 | ÷ | 6 | × | ( | 3 | x | + | 24 | ) |
| 4 | x | + | 8 | = | 5 | ÷ | 6 | × | 3 | x | + | 5 | ÷ | 6 | × | 24 |
| 4 | x | + | 8 | = | 5 2 | x | + | 20 |
| 4 | x | − | 5 2 | x | = | 20 | − | 8 |
3 2 | x | = | 20 | − | 8 |
3 2 | x | = | 12 |
| x | = | 12 | ÷ | 3 2 |
| = | 12 | × | 2 3 |
| = | 4 | × | 2 |
| x | = | 8 |
