9810 | ÷ | x | × | 3 2 | = | 9810 | ÷ | ( | x | − | 1 | ) |
方程两边同时乘以: | x | , | ( | x | − | 1 | ) |
9810 | × | 3 2 | ( | x | − | 1 | ) | = | 9810 | x |
9810 | × | 3 2 | x | − | 9810 | × | 3 2 | × | 1 | = | 9810 | x |
14715 | x | − | 14715 | = | 9810 | x |
14715 | x | − | 9810 | x | = | 14715 |
4905 | x | = | 14715 |
x | = | 14715 | ÷ | 4905 |
= | 14715 | × | 1 4905 |
= | 327 | × | 1 109 |
x | = | 327 109 |
x | = | 3 |
