( | 9149 | + | x | ) | ÷ | ( | 10875 | + | x | ) | = | 9 10 |
方程两边同时乘以: | ( | 10875 | + | x | ) |
( | 9149 | + | x | ) | = | 9 10 | ( | 10875 | + | x | ) |
9149 | + | x | = | 9 10 | ( | 10875 | + | x | ) |
9149 | + | x | = | 9 10 | × | 10875 | + | 9 10 | x |
9149 | + | x | = | 19575 2 | + | 9 10 | x |
x | − | 9 10 | x | = | 19575 2 | − | 9149 |
1 10 | x | = | 19575 2 | − | 9149 |
1 10 | x | = | 1277 2 |
x | = | 1277 2 | ÷ | 1 10 |
= | 1277 2 | × | 10 |
= | 1277 | × | 5 |
x | = | 6385 |
