X | ÷ | 126 | − | ( | 92 | − | X | ) | ÷ | 1000 | = | 81 200 |
方程左边 = | 1 126 | X | − | 92 | × | 1 1000 | + | X | × | 1 1000 |
= | 1 126 | X | − | 23 250 | + | X | × | 1 1000 |
= | 563 63000 | X | − | 23 250 |
563 63000 | X | − | 23 250 | = | 81 200 |
563 63000 | X | = | 81 200 | + | 23 250 |
563 63000 | X | = | 497 1000 |
X | = | 497 1000 | ÷ | 563 63000 |
= | 497 1000 | × | 63000 563 |
= | 497 | × | 63 563 |
X | = | 31311 563 |
X | = | 55.614565 |
