| ( | 301 10 | x | ) | ÷ | ( | x | + | 301 10 | ) | = | 8891 800 |
| 方程两边同时乘以: | ( | x | + | 301 10 | ) |
| ( | 301 10 | x | ) | = | 8891 800 | ( | x | + | 301 10 | ) |
301 10 | x | = | 8891 800 | ( | x | + | 301 10 | ) |
301 10 | x | = | 8891 800 | x | + | 8891 800 | × | 301 10 |
301 10 | x | = | 8891 800 | x | + | 2676191 8000 |
301 10 | x | − | 8891 800 | x | = | 2676191 8000 |
15189 800 | x | = | 2676191 8000 |
| x | = | 2676191 8000 | ÷ | 15189 800 |
