1973 100 | ÷ | ( | x | + | 1973 100 | ) | = | 2 5 |
| 方程两边同时乘以: | ( | x | + | 1973 100 | ) |
1973 100 | = | 2 5 | ( | x | + | 1973 100 | ) |
1973 100 | = | 2 5 | x | + | 2 5 | × | 1973 100 |
1973 100 | = | 2 5 | x | + | 1973 250 |
| - | 2 5 | x | = | 1973 250 | − | 1973 100 |
| - | 2 5 | x | = | - | 5919 500 |
5919 500 | = | 2 5 | x |
2 5 | x | = | 5919 500 |
| x | = | 5919 500 | ÷ | 2 5 |
| = | 5919 500 | × | 5 2 |
| = | 5919 100 | × | 1 2 |
| x | = | 5919 200 |
| x | = | 29.595 |
