x | − | 459 | − | x | × | 3 25 | = | ( | x | − | 459 | ) | × | 2 5 |
方程左边 = | 22 25 | x | − | 459 |
22 25 | x | − | 459 | = | ( | x | − | 459 | ) | × | 2 5 |
方程右边 = | x | × | 2 5 | − | 459 | × | 2 5 |
= | x | × | 2 5 | − | 918 5 |
22 25 | x | − | 459 | = | 2 5 | x | − | 918 5 |
22 25 | x | − | 2 5 | x | = | - | 918 5 | + | 459 |
12 25 | x | = | - | 918 5 | + | 459 |
12 25 | x | = | 1377 5 |
x | = | 1377 5 | ÷ | 12 25 |
= | 1377 5 | × | 25 12 |
= | 459 | × | 5 4 |
x | = | 2295 4 |
x | = | 573.75 |
