x | ÷ | 578 | + | ( | x | + | 4000 | ) | ÷ | 2080 | = | 48 | − | 26 |
方程左边 = | 1 578 | x | + | x | × | 1 2080 | + | 4000 | × | 1 2080 |
= | 1 578 | x | + | x | × | 1 2080 | + | 25 13 |
= | 1329 601120 | x | + | 25 13 |
1329 601120 | x | + | 25 13 | = | 48 | − | 26 |
方程右边 = | 22 |
1329 601120 | x | + | 25 13 | = | 22 |
1329 601120 | x | = | 22 | − | 25 13 |
1329 601120 | x | = | 261 13 |
x | = | 261 13 | ÷ | 1329 601120 |
= | 261 13 | × | 601120 1329 |
= | 87 | × | 46240 443 |
