| ( | 13 | ÷ | 17 | × | x | + | 1 | ) | ÷ | 48 | = | ( | 1 | − | x | ) | ÷ | 4 |
| 方程左边 = | 13 | ÷ | 17 | × | x | × | 1 48 | + | 1 | × | 1 48 |
| = | 13 816 | x | + | 1 48 |
13 816 | x | + | 1 48 | = | ( | 1 | − | x | ) | ÷ | 4 |
| 方程右边 = | 1 | × | 1 4 | − | x | × | 1 4 |
| = | 1 4 | − | x | × | 1 4 |
13 816 | x | + | 1 48 | = | 1 4 | − | 1 4 | x |
13 816 | x | + | 1 4 | x | = | 1 4 | − | 1 48 |
217 816 | x | = | 1 4 | − | 1 48 |
217 816 | x | = | 11 48 |
| x | = | 11 48 | ÷ | 217 816 |
| = | 11 48 | × | 816 217 |
| = | 11 | × | 17 217 |
| x | = | 187 217 |
