( | 1 5 | x | + | 424 | ) | + | ( | 21 100 | x | + | 212 | ) | = | 8966 |
方程左边 = | 1 5 | x | + | 424 | + | ( | 21 100 | x | + | 212 | ) |
= | 1 5 | x | + | 424 | + | 21 100 | x | + | 212 |
= | 41 100 | x | + | 636 |
41 100 | x | + | 636 | = | 8966 |
41 100 | x | = | 8966 | − | 636 |
41 100 | x | = | 8330 |
x | = | 8330 | ÷ | 41 100 |
= | 8330 | × | 100 41 |
x | = | 833000 41 |
x | = | 20317.073171 |
