( | 1 | + | 1 2 | x | ) | ÷ | ( | 1 | + | 5 | x | ) | = | 83 500 |
方程两边同时乘以: | ( | 1 | + | 5 | x | ) |
( | 1 | + | 1 2 | x | ) | = | 83 500 | ( | 1 | + | 5 | x | ) |
1 | + | 1 2 | x | = | 83 500 | ( | 1 | + | 5 | x | ) |
1 | + | 1 2 | x | = | 83 500 | × | 1 | + | 83 500 | × | 5 | x |
1 | + | 1 2 | x | = | 83 500 | + | 83 100 | x |
1 2 | x | - | 83 100 | x | = | 83 500 | - | 1 |
- | 33 100 | x | = | 83 500 | - | 1 |
- | 33 100 | x | = | - | 417 500 |
33 100 | x | = | 417 500 |
x | = | 417 500 | ÷ | 33 100 |
= | 417 500 | × | 100 33 |
= | 139 5 | × | 1 11 |
