x | = | 869 1000 | ÷ | ( | 853 1000 | + | 17 100 | ÷ | x | ) |
方程两边同时乘以: | ( | 853 1000 | + | 17 100 | ÷ | x | ) |
x | ( | 853 1000 | + | 17 100 | ÷ | x | ) | = | 869 1000 |
x | × | 853 1000 | + | x | × | 17 100 | ÷ | x | = | 869 1000 |
853 1000 | x | = | 869 1000 | − | 1 | × | 17 100 | ÷ | 1 |
853 1000 | x | = | 869 1000 | − | 17 100 |
853 1000 | x | = | 699 1000 |
x | = | 699 1000 | ÷ | 853 1000 |
= | 699 1000 | × | 1000 853 |
= | 699 | × | 1 853 |
x | = | 699 853 |
x | = | 0.819461 |
