| x | ÷ | ( | 69270833 | + | x | ) | = | 25 100 |
| 方程两边同时乘以: | ( | 69270833 | + | x | ) |
| x | = | 25 100 | ( | 69270833 | + | x | ) |
| x | = | 25 100 | × | 69270833 | + | 25 100 | x |
| x | = | 69270833 4 | + | 25 100 | x |
| x | − | 25 100 | x | = | 69270833 4 |
3 4 | x | = | 69270833 4 |
| x | = | 69270833 4 | ÷ | 3 4 |
| = | 69270833 4 | × | 4 3 |
| = | 69270833 | × | 1 3 |
| x | = | 69270833 3 |
| x | = | 23090277.666666999 |
