( | 26493 1000 | + | x | ) | × | 57 20 | = | 26493 1000 | + | 35139 500 | − | x |
方程左边 = | 26493 1000 | × | 57 20 | + | x | × | 57 20 |
= | 1510101 20000 | + | x | × | 57 20 |
1510101 20000 | + | 57 20 | x | = | 26493 1000 | + | 35139 500 | − | x |
方程右边 = | 96771 1000 | − | x |
1510101 20000 | + | 57 20 | x | = | 96771 1000 | − | x |
57 20 | x | + | x | = | 96771 1000 | − | 1510101 20000 |
77 20 | x | = | 96771 1000 | − | 1510101 20000 |
77 20 | x | = | 425319 20000 |
x | = | 425319 20000 | ÷ | 77 20 |
= | 425319 20000 | × | 20 77 |
= | 425319 1000 | × | 1 77 |
x | = | 425319 77000 |
