2319 | ÷ | ( | x | + | 2319 | ) | = | 2 5 |
方程两边同时乘以: | ( | x | + | 2319 | ) |
2319 | = | 2 5 | ( | x | + | 2319 | ) |
2319 | = | 2 5 | x | + | 2 5 | × | 2319 |
2319 | = | 2 5 | x | + | 4638 5 |
- | 2 5 | x | = | 4638 5 | − | 2319 |
- | 2 5 | x | = | - | 6957 5 |
6957 5 | = | 2 5 | x |
2 5 | x | = | 6957 5 |
x | = | 6957 5 | ÷ | 2 5 |
= | 6957 5 | × | 5 2 |
= | 6957 | × | 1 2 |
x | = | 6957 2 |
x | = | 3478.5 |
