600 | ( | x | − | 40 | ) | = | 700 | ( | x | − | 88 | ) |
方程左边 = | 600 | x | − | 600 | × | 40 |
= | 600 | x | − | 24000 |
600 | x | − | 24000 | = | 700 | ( | x | − | 88 | ) |
方程右边 = | 700 | x | − | 700 | × | 88 |
= | 700 | x | − | 61600 |
600 | x | − | 24000 | = | 700 | x | − | 61600 |
600 | x | − | 700 | x | = | - | 61600 | + | 24000 |
- | 100 | x | = | - | 61600 | + | 24000 |
- | 100 | x | = | - | 37600 |
37600 | = | 100 | x |
100 | x | = | 37600 |
x | = | 37600 | ÷ | 100 |
= | 37600 | × | 1 100 |
= | 376 | × | 1 |
x | = | 376 |
