223 100 | ÷ | ( | x | + | 1 | ) | = | 54 25 |
| 方程两边同时乘以: | ( | x | + | 1 | ) |
223 100 | = | 54 25 | ( | x | + | 1 | ) |
223 100 | = | 54 25 | x | + | 54 25 | × | 1 |
223 100 | = | 54 25 | x | + | 54 25 |
| - | 54 25 | x | = | 54 25 | − | 223 100 |
| - | 54 25 | x | = | - | 7 100 |
7 100 | = | 54 25 | x |
54 25 | x | = | 7 100 |
| x | = | 7 100 | ÷ | 54 25 |
| = | 7 100 | × | 25 54 |
| = | 7 4 | × | 1 54 |
