( | 40221 1000 | + | x | ) | × | 4 5 | = | 40221 1000 | + | 33621 500 | − | x |
方程左边 = | 40221 1000 | × | 4 5 | + | x | × | 4 5 |
= | 40221 1250 | + | x | × | 4 5 |
40221 1250 | + | 4 5 | x | = | 40221 1000 | + | 33621 500 | − | x |
方程右边 = | 107463 1000 | − | x |
40221 1250 | + | 4 5 | x | = | 107463 1000 | − | x |
4 5 | x | + | x | = | 107463 1000 | − | 40221 1250 |
9 5 | x | = | 107463 1000 | − | 40221 1250 |
9 5 | x | = | 376431 5000 |
x | = | 376431 5000 | ÷ | 9 5 |
= | 376431 5000 | × | 5 9 |
= | 125477 1000 | × | 1 3 |
