( | x | + | 180 | ) | ÷ | 45 | = | ( | x | - | 180 | ) | ÷ | 33 |
方程左边 = | x | × | 1 45 | + | 180 | × | 1 45 |
= | x | × | 1 45 | + | 4 |
1 45 | x | + | 4 | = | ( | x | - | 180 | ) | ÷ | 33 |
方程右边 = | x | × | 1 33 | - | 180 | × | 1 33 |
= | x | × | 1 33 | - | 60 11 |
1 45 | x | + | 4 | = | 1 33 | x | - | 60 11 |
1 45 | x | - | 1 33 | x | = | - | 60 11 | - | 4 |
- | 4 495 | x | = | - | 60 11 | - | 4 |
- | 4 495 | x | = | - | 104 11 |
4 495 | x | = | 104 11 |
x | = | 104 11 | ÷ | 4 495 |
= | 104 11 | × | 495 4 |
= | 26 | × | 45 |
x | = | 1170 |
