X | ÷ | ( | X | + | 286369 500 | ) | = | 5 100 |
方程两边同时乘以: | ( | X | + | 286369 500 | ) |
X | = | 5 100 | ( | X | + | 286369 500 | ) |
X | = | 5 100 | X | + | 5 100 | × | 286369 500 |
X | = | 5 100 | X | + | 286369 10000 |
X | − | 5 100 | X | = | 286369 10000 |
19 20 | X | = | 286369 10000 |
X | = | 286369 10000 | ÷ | 19 20 |
= | 286369 10000 | × | 20 19 |
= | 286369 500 | × | 1 19 |
X | = | 286369 9500 |
X | = | 30.144105 |
