( | 26493 1000 | + | x | ) | × | 49 20 | = | 26493 1000 | + | 35139 500 | − | x |
方程左边 = | 26493 1000 | × | 49 20 | + | x | × | 49 20 |
= | 1298157 20000 | + | x | × | 49 20 |
1298157 20000 | + | 49 20 | x | = | 26493 1000 | + | 35139 500 | − | x |
方程右边 = | 96771 1000 | − | x |
1298157 20000 | + | 49 20 | x | = | 96771 1000 | − | x |
49 20 | x | + | x | = | 96771 1000 | − | 1298157 20000 |
69 20 | x | = | 96771 1000 | − | 1298157 20000 |
69 20 | x | = | 637263 20000 |
x | = | 637263 20000 | ÷ | 69 20 |
= | 637263 20000 | × | 20 69 |
= | 212421 1000 | × | 1 23 |
