( | x | + | 135 | ) | ÷ | x | = | 1256 5 | ÷ | 4553 25 |
方程两边同时乘以: | x |
( | x | + | 135 | ) | = | 1256 5 | ÷ | 4553 25 | × | x |
x | + | 135 | = | 1256 5 | ÷ | 4553 25 | × | x |
x | + | 135 | = | 6280 4553 | x |
x | − | 6280 4553 | x | = | - | 135 |
- | 1727 4553 | x | = | - | 135 |
135 | = | 1727 4553 | x |
1727 4553 | x | = | 135 |
x | = | 135 | ÷ | 1727 4553 |
= | 135 | × | 4553 1727 |
