( | x | + | 4 5 | ) | ÷ | ( | x | − | 17 10 | ) | = | 5 | ÷ | 3 |
方程两边同时乘以: | ( | x | − | 17 10 | ) |
( | x | + | 4 5 | ) | = | 5 | ÷ | 3 | × | ( | x | − | 17 10 | ) |
x | + | 4 5 | = | 5 | ÷ | 3 | × | ( | x | − | 17 10 | ) |
x | + | 4 5 | = | 5 | ÷ | 3 | × | x | − | 5 | ÷ | 3 | × | 17 10 |
x | + | 4 5 | = | 5 3 | x | − | 17 6 |
x | − | 5 3 | x | = | - | 17 6 | − | 4 5 |
- | 2 3 | x | = | - | 17 6 | − | 4 5 |
- | 2 3 | x | = | - | 109 30 |
109 30 | = | 2 3 | x |
2 3 | x | = | 109 30 |
x | = | 109 30 | ÷ | 2 3 |
= | 109 30 | × | 3 2 |
= | 109 10 | × | 1 2 |
x | = | 109 20 |
x | = | 5.45 |
