( | 40221 1000 | + | x | ) | × | 39 20 | = | 40221 1000 | + | 36121 500 | − | x |
方程左边 = | 40221 1000 | × | 39 20 | + | x | × | 39 20 |
= | 1568619 20000 | + | x | × | 39 20 |
1568619 20000 | + | 39 20 | x | = | 40221 1000 | + | 36121 500 | − | x |
方程右边 = | 112463 1000 | − | x |
1568619 20000 | + | 39 20 | x | = | 112463 1000 | − | x |
39 20 | x | + | x | = | 112463 1000 | − | 1568619 20000 |
59 20 | x | = | 112463 1000 | − | 1568619 20000 |
59 20 | x | = | 680641 20000 |
x | = | 680641 20000 | ÷ | 59 20 |
= | 680641 20000 | × | 20 59 |
= | 680641 1000 | × | 1 59 |
x | = | 680641 59000 |
