1000 | p | × | 25 100 | = | 1000 | p | ( | 1 | − | 5 100 | ) | − | 1000 | × | 50 | + | 25000 |
方程左边 = | 250 | p |
250 | p | = | 1000 | p | ( | 1 | − | 5 100 | ) | − | 1000 | × | 50 | + | 25000 |
方程右边 = | 1000 | p | ( | 1 | − | 5 100 | ) | − | 50000 | + | 25000 |
= | 1000 | p | ( | 1 | − | 5 100 | ) | − | 25000 |

方程右边 = | 1000 | p | × | 1 | − | 1000 | p | × | 5 100 | − | 25000 |
= | 1000 | p | − | 50 | p | − | 25000 |
= | 950 | p | − | 25000 |
250 | p | = | 950 | p | − | 25000 |
250 | p | − | 950 | p | = | - | 25000 |
- | 700 | p | = | - | 25000 |
25000 | = | 700 | p |
700 | p | = | 25000 |
p | = | 25000 | ÷ | 700 |
= | 25000 | × | 1 700 |
= | 250 | × | 1 7 |
p | = | 250 7 |
