( | 5499 10 | + | X | ) | ÷ | ( | 11673 10 | + | X | ) | = | 3 5 |
方程两边同时乘以: | ( | 11673 10 | + | X | ) |
( | 5499 10 | + | X | ) | = | 3 5 | ( | 11673 10 | + | X | ) |
5499 10 | + | X | = | 3 5 | ( | 11673 10 | + | X | ) |
5499 10 | + | X | = | 3 5 | × | 11673 10 | + | 3 5 | X |
5499 10 | + | X | = | 35019 50 | + | 3 5 | X |
X | − | 3 5 | X | = | 35019 50 | − | 5499 10 |
2 5 | X | = | 35019 50 | − | 5499 10 |
2 5 | X | = | 3762 25 |
X | = | 3762 25 | ÷ | 2 5 |
= | 3762 25 | × | 5 2 |
= | 1881 5 | × | 1 |
X | = | 1881 5 |
X | = | 376.2 |
