| ( | x | + | 1039 | ) | ÷ | ( | x | + | 1123 | ) | = | 93 100 |
| 方程两边同时乘以: | ( | x | + | 1123 | ) |
| ( | x | + | 1039 | ) | = | 93 100 | ( | x | + | 1123 | ) |
| x | + | 1039 | = | 93 100 | ( | x | + | 1123 | ) |
| x | + | 1039 | = | 93 100 | x | + | 93 100 | × | 1123 |
| x | + | 1039 | = | 93 100 | x | + | 104439 100 |
| x | − | 93 100 | x | = | 104439 100 | − | 1039 |
7 100 | x | = | 104439 100 | − | 1039 |
7 100 | x | = | 539 100 |
| x | = | 539 100 | ÷ | 7 100 |
| = | 539 100 | × | 100 7 |
| = | 77 | × | 1 |
| x | = | 77 |
