600 | x | ÷ | ( | 1800 | ( | 1 | − | x | ) | ) | = | 3 50 |
方程两边同时乘以: | ( | 1800 | ( | 1 | − | x | ) | ) |
600 | x | = | 3 50 | ( | 1800 | ( | 1 | − | x | ) | ) |
600 | x | = | 3 50 | × | 1800 | ( | 1 | − | x | ) |
600 | x | = | 108 | ( | 1 | − | x | ) |
600 | x | = | 108 | × | 1 | − | 108 | x |
600 | x | = | 108 | − | 108 | x |
600 | x | + | 108 | x | = | 108 |
708 | x | = | 108 |
x | = | 108 | ÷ | 708 |
= | 108 | × | 1 708 |
= | 9 | × | 1 59 |
x | = | 9 59 |
x | = | 0.152542 |
