( | 24000 | − | X | ) | ÷ | X | × | 100 100 | = | 20 100 |
方程两边同时乘以: | X |
( | 24000 | − | X | ) | × | 100 100 | = | 20 100 | X |
24000 | × | 100 100 | − | X | × | 100 100 | = | 20 100 | X |
24000 | − | X | × | 100 100 | = | 20 100 | X |
- | 100 100 | X | − | 20 100 | X | = | - | 24000 |
- | 6 5 | X | = | - | 24000 |
24000 | = | 6 5 | X |
6 5 | X | = | 24000 |
X | = | 24000 | ÷ | 6 5 |
= | 24000 | × | 5 6 |
= | 4000 | × | 5 |
X | = | 20000 |
