方程右边 = | 55503 500 | − | x |
334917 10000 | + | 17 20 | x | = | 55503 500 | − | x |
17 20 | x | + | x | = | 55503 500 | − | 334917 10000 |
37 20 | x | = | 55503 500 | − | 334917 10000 |
37 20 | x | = | 775143 10000 |
x | = | 775143 10000 | ÷ | 37 20 |
= | 775143 10000 | × | 20 37 |
= | 775143 500 | × | 1 37 |
