方程右边 = | 4600 | ( | 82600 | x | − | 4085 | ) | ÷ | 6000 |
= | 23 30 | ( | 82600 | x | − | 4085 | ) |
= | 23 30 | × | 82600 | x | − | 23 30 | × | 4085 |
= | 189980 3 | x | − | 18791 6 |
9020 | + | 20000 | x | = | 189980 3 | x | − | 18791 6 |
20000 | x | − | 189980 3 | x | = | - | 18791 6 | − | 9020 |
- | 129980 3 | x | = | - | 18791 6 | − | 9020 |
- | 129980 3 | x | = | - | 72911 6 |
72911 6 | = | 129980 3 | x |
129980 3 | x | = | 72911 6 |
x | = | 72911 6 | ÷ | 129980 3 |
= | 72911 6 | × | 3 129980 |
= | 72911 2 | × | 1 129980 |
