( | 1000 | + | x | ) | ÷ | ( | 1000 | ÷ | 223 100 | + | x | ) | = | 7 4 |
方程两边同时乘以: | ( | 1000 | ÷ | 223 100 | + | x | ) |
( | 1000 | + | x | ) | = | 7 4 | ( | 1000 | ÷ | 223 100 | + | x | ) |
1000 | + | x | = | 7 4 | ( | 1000 | ÷ | 223 100 | + | x | ) |
1000 | + | x | = | 7 4 | × | 1000 | ÷ | 223 100 | + | 7 4 | x |
1000 | + | x | = | 175000 223 | + | 7 4 | x |
x | − | 7 4 | x | = | 175000 223 | − | 1000 |
- | 3 4 | x | = | 175000 223 | − | 1000 |
- | 3 4 | x | = | - | 48000 223 |
48000 223 | = | 3 4 | x |
3 4 | x | = | 48000 223 |
x | = | 48000 223 | ÷ | 3 4 |
= | 48000 223 | × | 4 3 |
= | 16000 223 | × | 4 |
x | = | 64000 223 |
x | = | 286.995516 |
