| ( | 1148 | + | x | ) | ÷ | ( | 1708 | + | x | ) | = | 79 100 |
| 方程两边同时乘以: | ( | 1708 | + | x | ) |
| ( | 1148 | + | x | ) | = | 79 100 | ( | 1708 | + | x | ) |
| 1148 | + | x | = | 79 100 | ( | 1708 | + | x | ) |
| 1148 | + | x | = | 79 100 | × | 1708 | + | 79 100 | x |
| 1148 | + | x | = | 33733 25 | + | 79 100 | x |
| x | − | 79 100 | x | = | 33733 25 | − | 1148 |
21 100 | x | = | 33733 25 | − | 1148 |
21 100 | x | = | 5033 25 |
| x | = | 5033 25 | ÷ | 21 100 |
| = | 5033 25 | × | 100 21 |
| = | 719 | × | 4 3 |
