方程右边 = | 15459 125 | − | x |
775083 10000 | + | 59 20 | x | = | 15459 125 | − | x |
59 20 | x | + | x | = | 15459 125 | − | 775083 10000 |
79 20 | x | = | 15459 125 | − | 775083 10000 |
79 20 | x | = | 461637 10000 |
x | = | 461637 10000 | ÷ | 79 20 |
= | 461637 10000 | × | 20 79 |
= | 461637 500 | × | 1 79 |
