( | 19701 500 | + | x | ) | × | 47 20 | = | 19701 500 | + | 9013 125 | − | x |
方程左边 = | 19701 500 | × | 47 20 | + | x | × | 47 20 |
= | 925947 10000 | + | x | × | 47 20 |
925947 10000 | + | 47 20 | x | = | 19701 500 | + | 9013 125 | − | x |
方程右边 = | 55753 500 | − | x |
925947 10000 | + | 47 20 | x | = | 55753 500 | − | x |
47 20 | x | + | x | = | 55753 500 | − | 925947 10000 |
67 20 | x | = | 55753 500 | − | 925947 10000 |
67 20 | x | = | 189113 10000 |
x | = | 189113 10000 | ÷ | 67 20 |
= | 189113 10000 | × | 20 67 |
= | 189113 500 | × | 1 67 |
x | = | 189113 33500 |
