( | 65 | + | x | ) | ÷ | ( | 95 | + | x | ) | = | 309 500 |
方程两边同时乘以: | ( | 95 | + | x | ) |
( | 65 | + | x | ) | = | 309 500 | ( | 95 | + | x | ) |
65 | + | x | = | 309 500 | ( | 95 | + | x | ) |
65 | + | x | = | 309 500 | × | 95 | + | 309 500 | x |
65 | + | x | = | 5871 100 | + | 309 500 | x |
x | − | 309 500 | x | = | 5871 100 | − | 65 |
191 500 | x | = | 5871 100 | − | 65 |
191 500 | x | = | - | 629 100 |
x | = | - | 629 100 | ÷ | 191 500 |
= | - | 629 100 | × | 500 191 |
= | - | 629 | × | 5 191 |
x | = | - | 3145 191 |
x | = | - 16.465969 |
