方程右边 = | 22057 50 | × | 1 | − | 22057 50 | x | + | 60 |
= | 22057 50 | − | 22057 50 | x | + | 60 |
= | 25057 50 | − | 22057 50 | x |
381 | = | 25057 50 | − | 22057 50 | x |
22057 50 | x | = | 25057 50 | − | 381 |
22057 50 | x | = | 6007 50 |
x | = | 6007 50 | ÷ | 22057 50 |
= | 6007 50 | × | 50 22057 |
= | 6007 | × | 1 22057 |
x | = | 6007 22057 |
