( | 160 | + | x | ) | ÷ | ( | 96 | + | x | ) | = | 309 500 |
方程两边同时乘以: | ( | 96 | + | x | ) |
( | 160 | + | x | ) | = | 309 500 | ( | 96 | + | x | ) |
160 | + | x | = | 309 500 | ( | 96 | + | x | ) |
160 | + | x | = | 309 500 | × | 96 | + | 309 500 | x |
160 | + | x | = | 7416 125 | + | 309 500 | x |
x | − | 309 500 | x | = | 7416 125 | − | 160 |
191 500 | x | = | 7416 125 | − | 160 |
191 500 | x | = | - | 12584 125 |
x | = | - | 12584 125 | ÷ | 191 500 |
= | - | 12584 125 | × | 500 191 |
= | - | 12584 | × | 4 191 |
x | = | - | 50336 191 |
x | = | - 263.539267 |
