X | + | ( | 5000 | − | 120 | X | ) | ÷ | 10000 | = | 1727 500 |
方程左边 = | X | + | 5000 | × | 1 10000 | − | 120 | X | × | 1 10000 |
= | X | + | 1 2 | − | 3 250 | X |
= | 247 250 | X | + | 1 2 |
247 250 | X | + | 1 2 | = | 1727 500 |
247 250 | X | = | 1727 500 | − | 1 2 |
247 250 | X | = | 1477 500 |
X | = | 1477 500 | ÷ | 247 250 |
= | 1477 500 | × | 250 247 |
= | 1477 2 | × | 1 247 |
X | = | 1477 494 |
X | = | 2.989879 |
