( | 650 | + | X | ) | ÷ | ( | 1625 4 | + | X | ) | = | 7 5 |
方程两边同时乘以: | ( | 1625 4 | + | X | ) |
( | 650 | + | X | ) | = | 7 5 | ( | 1625 4 | + | X | ) |
650 | + | X | = | 7 5 | ( | 1625 4 | + | X | ) |
650 | + | X | = | 7 5 | × | 1625 4 | + | 7 5 | X |
650 | + | X | = | 2275 4 | + | 7 5 | X |
X | − | 7 5 | X | = | 2275 4 | − | 650 |
- | 2 5 | X | = | 2275 4 | − | 650 |
- | 2 5 | X | = | - | 325 4 |
325 4 | = | 2 5 | X |
2 5 | X | = | 325 4 |
X | = | 325 4 | ÷ | 2 5 |
= | 325 4 | × | 5 2 |
X | = | 1625 8 |
X | = | 203.125 |
