| 方程左边 = | 4 7 | x | − | 48 |
4 7 | x | − | 48 | = | ( | x | − | 48 | ) | × | 2 | ÷ | 5 |
| 方程右边 = | ( | x | − | 48 | ) | × | 2 5 |

| 方程右边 = | x | × | 2 5 | − | 48 | × | 2 5 |
| = | x | × | 2 5 | − | 96 5 |
4 7 | x | − | 48 | = | 2 5 | x | − | 96 5 |
4 7 | x | − | 2 5 | x | = | - | 96 5 | + | 48 |
6 35 | x | = | - | 96 5 | + | 48 |
6 35 | x | = | 144 5 |
| x | = | 144 5 | ÷ | 6 35 |
| = | 144 5 | × | 35 6 |
