| ( | x | − | 5 | ) | ÷ | ( | 119 25 | x | + | 2 | ) | = | 3 100 |
| 方程两边同时乘以: | ( | 119 25 | x | + | 2 | ) |
| ( | x | − | 5 | ) | = | 3 100 | ( | 119 25 | x | + | 2 | ) |
| x | − | 5 | = | 3 100 | ( | 119 25 | x | + | 2 | ) |
| x | − | 5 | = | 3 100 | × | 119 25 | x | + | 3 100 | × | 2 |
| x | − | 5 | = | 357 2500 | x | + | 3 50 |
| x | − | 357 2500 | x | = | 3 50 | + | 5 |
2143 2500 | x | = | 3 50 | + | 5 |
2143 2500 | x | = | 253 50 |
| x | = | 253 50 | ÷ | 2143 2500 |
| = | 253 50 | × | 2500 2143 |
| = | 253 | × | 50 2143 |
| x | = | 12650 2143 |
