( | x | − | 2000 | ) | × | 10 100 | − | 25 | = | 5539 100 |
方程左边 = | x | × | 10 100 | − | 2000 | × | 10 100 | − | 25 |
= | x | × | 10 100 | − | 200 | − | 25 |
= | 10 100 | x | − | 225 |
10 100 | x | − | 225 | = | 5539 100 |
10 100 | x | = | 5539 100 | + | 225 |
10 100 | x | = | 28039 100 |
x | = | 28039 100 | ÷ | 10 100 |
= | 28039 100 | × | 100 10 |
= | 28039 | × | 1 10 |
x | = | 28039 10 |
x | = | 2803.9 |
