| ( | 24 | + | 2 | x | ) | ÷ | ( | 26 | + | x | ) | = | 19 10 |
| 方程两边同时乘以: | ( | 26 | + | x | ) |
| ( | 24 | + | 2 | x | ) | = | 19 10 | ( | 26 | + | x | ) |
| 24 | + | 2 | x | = | 19 10 | ( | 26 | + | x | ) |
| 24 | + | 2 | x | = | 19 10 | × | 26 | + | 19 10 | x |
| 24 | + | 2 | x | = | 247 5 | + | 19 10 | x |
| 2 | x | − | 19 10 | x | = | 247 5 | − | 24 |
1 10 | x | = | 247 5 | − | 24 |
1 10 | x | = | 127 5 |
| x | = | 127 5 | ÷ | 1 10 |
| = | 127 5 | × | 10 |
| = | 127 | × | 2 |
| x | = | 254 |
