x | ÷ | ( | 385 | − | x | − | 903 50 | ) | = | 1 5 |
方程两边同时乘以: | ( | 385 | − | x | − | 903 50 | ) |
x | = | 1 5 | ( | 385 | − | x | − | 903 50 | ) |
x | = | 1 5 | × | 385 | − | 1 5 | x | − | 1 5 | × | 903 50 |
x | = | 77 | − | 1 5 | x | − | 903 250 |
x | = | 18347 250 | − | 1 5 | x |
x | + | 1 5 | x | = | 18347 250 |
6 5 | x | = | 18347 250 |
x | = | 18347 250 | ÷ | 6 5 |
= | 18347 250 | × | 5 6 |
= | 18347 50 | × | 1 6 |
x | = | 18347 300 |
x | = | 61.156667 |
