( | 40221 1000 | + | x | ) | × | 27 20 | = | 40221 1000 | + | 36121 500 | − | x |
方程左边 = | 40221 1000 | × | 27 20 | + | x | × | 27 20 |
= | 1085967 20000 | + | x | × | 27 20 |
1085967 20000 | + | 27 20 | x | = | 40221 1000 | + | 36121 500 | − | x |
方程右边 = | 112463 1000 | − | x |
1085967 20000 | + | 27 20 | x | = | 112463 1000 | − | x |
27 20 | x | + | x | = | 112463 1000 | − | 1085967 20000 |
47 20 | x | = | 112463 1000 | − | 1085967 20000 |
47 20 | x | = | 1163293 20000 |
x | = | 1163293 20000 | ÷ | 47 20 |
= | 1163293 20000 | × | 20 47 |
= | 1163293 1000 | × | 1 47 |
x | = | 1163293 47000 |
