- | 4 | x | + | 1 10 | ( | 25000 | − | x | ) | = | 2480 |
方程左边 = | - | 4 | x | + | 1 10 | × | 25000 | − | 1 10 | x |
= | - | 4 | x | + | 2500 | − | 1 10 | x |
= | - | 41 10 | x | + | 2500 |
- | 41 10 | x | + | 2500 | = | 2480 |
- | 41 10 | x | = | 2480 | − | 2500 |
- | 41 10 | x | = | - | 20 |
20 | = | 41 10 | x |
41 10 | x | = | 20 |
x | = | 20 | ÷ | 41 10 |
= | 20 | × | 10 41 |
x | = | 200 41 |
x | = | 4.878049 |
