( | 26307 1000 | + | x | ) | × | 9 4 | = | 52613 1000 | + | 3561 50 | − | x |
方程左边 = | 26307 1000 | × | 9 4 | + | x | × | 9 4 |
= | 236763 4000 | + | x | × | 9 4 |
236763 4000 | + | 9 4 | x | = | 52613 1000 | + | 3561 50 | − | x |
方程右边 = | 123833 1000 | − | x |
236763 4000 | + | 9 4 | x | = | 123833 1000 | − | x |
9 4 | x | + | x | = | 123833 1000 | − | 236763 4000 |
13 4 | x | = | 123833 1000 | − | 236763 4000 |
13 4 | x | = | 258569 4000 |
x | = | 258569 4000 | ÷ | 13 4 |
= | 258569 4000 | × | 4 13 |
= | 258569 1000 | × | 1 13 |
x | = | 258569 13000 |
