5 200 | ÷ | ( | x | − | 35 200 | ) | = | 2 | ÷ | 3 |
方程两边同时乘以: | ( | x | − | 35 200 | ) |
5 200 | = | 2 | ÷ | 3 | × | ( | x | − | 35 200 | ) |
5 200 | = | 2 | ÷ | 3 | × | x | − | 2 | ÷ | 3 | × | 35 200 |
5 200 | = | 2 3 | x | − | 7 60 |
- | 2 3 | x | = | - | 7 60 | − | 5 200 |
- | 2 3 | x | = | - | 17 120 |
17 120 | = | 2 3 | x |
2 3 | x | = | 17 120 |
x | = | 17 120 | ÷ | 2 3 |
= | 17 120 | × | 3 2 |
= | 17 40 | × | 1 2 |
x | = | 17 80 |
x | = | 0.2125 |
