( | 2937 5 | − | X | ) | ( | 50 | ÷ | 60 | ) | = | 192 |
方程左边 = | 2937 5 | ( | 50 | ÷ | 60 | ) | − | X | ( | 50 | ÷ | 60 | ) |
= | 2937 5 | × | 50 | ÷ | 60 | − | X | ( | 50 | ÷ | 60 | ) |
= | 979 2 | − | X | ( | 50 | ÷ | 60 | ) |
= | 979 2 | − | X | × | 50 | ÷ | 60 |
= | 979 2 | − | X | × | 5 6 |
979 2 | − | 5 6 | X | = | 192 |
- | 5 6 | X | = | 192 | − | 979 2 |
- | 5 6 | X | = | - | 595 2 |
595 2 | = | 5 6 | X |
5 6 | X | = | 595 2 |
X | = | 595 2 | ÷ | 5 6 |
= | 595 2 | × | 6 5 |
= | 119 | × | 3 |
X | = | 357 |
