( | 19701 500 | + | x | ) | × | 39 20 | = | 19701 500 | + | 17901 250 | − | x |
方程左边 = | 19701 500 | × | 39 20 | + | x | × | 39 20 |
= | 768339 10000 | + | x | × | 39 20 |
768339 10000 | + | 39 20 | x | = | 19701 500 | + | 17901 250 | − | x |
方程右边 = | 55503 500 | − | x |
768339 10000 | + | 39 20 | x | = | 55503 500 | − | x |
39 20 | x | + | x | = | 55503 500 | − | 768339 10000 |
59 20 | x | = | 55503 500 | − | 768339 10000 |
59 20 | x | = | 341721 10000 |
x | = | 341721 10000 | ÷ | 59 20 |
= | 341721 10000 | × | 20 59 |
= | 341721 500 | × | 1 59 |
x | = | 341721 29500 |
