| 1 | ÷ | ( | x | + | 3 10 | ) | = | 4 25 |
| 方程两边同时乘以: | ( | x | + | 3 10 | ) |
| 1 | = | 4 25 | ( | x | + | 3 10 | ) |
| 1 | = | 4 25 | x | + | 4 25 | × | 3 10 |
| 1 | = | 4 25 | x | + | 6 125 |
| - | 4 25 | x | = | 6 125 | − | 1 |
| - | 4 25 | x | = | - | 119 125 |
119 125 | = | 4 25 | x |
4 25 | x | = | 119 125 |
| x | = | 119 125 | ÷ | 4 25 |
| = | 119 125 | × | 25 4 |
| = | 119 5 | × | 1 4 |
| x | = | 119 20 |
| x | = | 5.95 |
