( | x | − | 100 | ) | ÷ | 100 | + | 24 100 | = | ( | x | − | 85 | ) | ÷ | 85 |
方程左边 = | x | × | 1 100 | − | 100 | × | 1 100 | + | 24 100 |
= | x | × | 1 100 | − | 1 | + | 24 100 |
= | 1 100 | x | − | 19 25 |
1 100 | x | − | 19 25 | = | ( | x | − | 85 | ) | ÷ | 85 |
方程右边 = | x | × | 1 85 | − | 85 | × | 1 85 |
= | x | × | 1 85 | − | 1 |
1 100 | x | − | 19 25 | = | 1 85 | x | − | 1 |
1 100 | x | − | 1 85 | x | = | - | 1 | + | 19 25 |
- | 3 1700 | x | = | - | 1 | + | 19 25 |
- | 3 1700 | x | = | - | 6 25 |
6 25 | = | 3 1700 | x |
3 1700 | x | = | 6 25 |
x | = | 6 25 | ÷ | 3 1700 |
= | 6 25 | × | 1700 3 |
= | 2 | × | 68 |
x | = | 136 |
