( | 50 | + | x | ) | ÷ | ( | 25 | + | x | ) | = | 17 10 |
方程两边同时乘以: | ( | 25 | + | x | ) |
( | 50 | + | x | ) | = | 17 10 | ( | 25 | + | x | ) |
50 | + | x | = | 17 10 | ( | 25 | + | x | ) |
50 | + | x | = | 17 10 | × | 25 | + | 17 10 | x |
50 | + | x | = | 85 2 | + | 17 10 | x |
x | − | 17 10 | x | = | 85 2 | − | 50 |
- | 7 10 | x | = | 85 2 | − | 50 |
- | 7 10 | x | = | - | 15 2 |
15 2 | = | 7 10 | x |
7 10 | x | = | 15 2 |
x | = | 15 2 | ÷ | 7 10 |
= | 15 2 | × | 10 7 |
= | 15 | × | 5 7 |
x | = | 75 7 |
x | = | 10.714286 |
