| ( | 209 500000 | + | 2683 3125 | x | ) | ÷ | ( | 1 | + | 851 10000 | x | ) | = | 4949 6250 |
| 方程两边同时乘以: | ( | 1 | + | 851 10000 | x | ) |
| ( | 209 500000 | + | 2683 3125 | x | ) | = | 4949 6250 | ( | 1 | + | 851 10000 | x | ) |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | ( | 1 | + | 851 10000 | x | ) |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | × | 1 | + | 4949 6250 | × | 851 10000 | x |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | + | 4211599 62500000 | x |
2683 3125 | x | − | 4211599 62500000 | x | = | 4949 6250 | − | 209 500000 |
| x1=1 | ,它是方程的增解。 |
