方程左边 = | 50000 | p | − | 50000 | p | × | 1 | + | 50000 | p | × | 5 100 | − | 617500 |
= | 50000 | p | − | 50000 | p | + | 2500 | p | − | 617500 |
= | 2500 | p | − | 617500 |
2500 | p | − | 617500 | = | 103550 |
2500 | p | = | 103550 | + | 617500 |
2500 | p | = | 721050 |
p | = | 721050 | ÷ | 2500 |
= | 721050 | × | 1 2500 |
