( | 13163 500 | + | x | ) | × | 47 20 | = | 13163 250 | + | 35639 500 | − | x |
方程左边 = | 13163 500 | × | 47 20 | + | x | × | 47 20 |
= | 618661 10000 | + | x | × | 47 20 |
618661 10000 | + | 47 20 | x | = | 13163 250 | + | 35639 500 | − | x |
方程右边 = | 12393 100 | − | x |
618661 10000 | + | 47 20 | x | = | 12393 100 | − | x |
47 20 | x | + | x | = | 12393 100 | − | 618661 10000 |
67 20 | x | = | 12393 100 | − | 618661 10000 |
67 20 | x | = | 620639 10000 |
x | = | 620639 10000 | ÷ | 67 20 |
= | 620639 10000 | × | 20 67 |
= | 620639 500 | × | 1 67 |
x | = | 620639 33500 |
