X | + | ( | 5000 | − | 60 | X | ) | ÷ | 1000 | = | 1727 500 |
方程左边 = | X | + | 5000 | × | 1 1000 | − | 60 | X | × | 1 1000 |
= | X | + | 5 | − | 3 50 | X |
= | 47 50 | X | + | 5 |
47 50 | X | + | 5 | = | 1727 500 |
47 50 | X | = | 1727 500 | − | 5 |
47 50 | X | = | - | 773 500 |
X | = | - | 773 500 | ÷ | 47 50 |
= | - | 773 500 | × | 50 47 |
= | - | 773 10 | × | 1 47 |
X | = | - | 773 470 |
X | = | - 1.644681 |
