( | 13137 500 | + | x | ) | × | 47 20 | = | 52549 1000 | + | 71123 1000 | − | x |
方程左边 = | 13137 500 | × | 47 20 | + | x | × | 47 20 |
= | 617439 10000 | + | x | × | 47 20 |
617439 10000 | + | 47 20 | x | = | 52549 1000 | + | 71123 1000 | − | x |
方程右边 = | 15459 125 | − | x |
617439 10000 | + | 47 20 | x | = | 15459 125 | − | x |
47 20 | x | + | x | = | 15459 125 | − | 617439 10000 |
67 20 | x | = | 15459 125 | − | 617439 10000 |
67 20 | x | = | 619281 10000 |
x | = | 619281 10000 | ÷ | 67 20 |
= | 619281 10000 | × | 20 67 |
= | 9243 500 | × | 1 |
x | = | 9243 500 |
x | = | 18.486 |
