| ( | x | − | 48 | ) | ÷ | 4 | = | ( | x | + | 8 | ) | ÷ | 6 |
| 方程左边 = | x | × | 1 4 | − | 48 | × | 1 4 |
| = | x | × | 1 4 | − | 12 |
1 4 | x | − | 12 | = | ( | x | + | 8 | ) | ÷ | 6 |
| 方程右边 = | x | × | 1 6 | + | 8 | × | 1 6 |
| = | x | × | 1 6 | + | 4 3 |
1 4 | x | − | 12 | = | 1 6 | x | + | 4 3 |
1 4 | x | − | 1 6 | x | = | 4 3 | + | 12 |
1 12 | x | = | 4 3 | + | 12 |
1 12 | x | = | 40 3 |
| x | = | 40 3 | ÷ | 1 12 |
| = | 40 3 | × | 12 |
| = | 40 | × | 4 |
| x | = | 160 |
