( | 825 | + | x | ) | ÷ | ( | 873 | + | x | ) | = | 2421 2500 |
方程两边同时乘以: | ( | 873 | + | x | ) |
( | 825 | + | x | ) | = | 2421 2500 | ( | 873 | + | x | ) |
825 | + | x | = | 2421 2500 | ( | 873 | + | x | ) |
825 | + | x | = | 2421 2500 | × | 873 | + | 2421 2500 | x |
825 | + | x | = | 2113533 2500 | + | 2421 2500 | x |
x | − | 2421 2500 | x | = | 2113533 2500 | − | 825 |
79 2500 | x | = | 2113533 2500 | − | 825 |
79 2500 | x | = | 51033 2500 |
x | = | 51033 2500 | ÷ | 79 2500 |
= | 51033 2500 | × | 2500 79 |
= | 51033 | × | 1 79 |
x | = | 51033 79 |
x | = | 645.987342 |
