X | ÷ | ( | X | + | 301439 500 | ) | = | 10 100 |
方程两边同时乘以: | ( | X | + | 301439 500 | ) |
X | = | 10 100 | ( | X | + | 301439 500 | ) |
X | = | 10 100 | X | + | 10 100 | × | 301439 500 |
X | = | 10 100 | X | + | 301439 5000 |
X | − | 10 100 | X | = | 301439 5000 |
9 10 | X | = | 301439 5000 |
X | = | 301439 5000 | ÷ | 9 10 |
= | 301439 5000 | × | 10 9 |
= | 301439 500 | × | 1 9 |
X | = | 301439 4500 |
X | = | 66.986444 |
