( | 26293 1000 | + | x | ) | × | 61 20 | = | 26293 1000 | + | 35639 500 | − | x |
方程左边 = | 26293 1000 | × | 61 20 | + | x | × | 61 20 |
= | 1603873 20000 | + | x | × | 61 20 |
1603873 20000 | + | 61 20 | x | = | 26293 1000 | + | 35639 500 | − | x |
方程右边 = | 97571 1000 | − | x |
1603873 20000 | + | 61 20 | x | = | 97571 1000 | − | x |
61 20 | x | + | x | = | 97571 1000 | − | 1603873 20000 |
81 20 | x | = | 97571 1000 | − | 1603873 20000 |
81 20 | x | = | 347547 20000 |
x | = | 347547 20000 | ÷ | 81 20 |
= | 347547 20000 | × | 20 81 |
= | 115849 1000 | × | 1 27 |
x | = | 115849 27000 |
