X | ÷ | 4352 | × | 7 10 | = | 1 5 | ( | 1 | − | X | ÷ | 4352 | × | 7 10 | ) |
方程左边 = | X | × | 7 43520 |
7 43520 | X | = | 1 5 | ( | 1 | − | X | ÷ | 4352 | × | 7 10 | ) |
方程右边 = | 1 5 | × | 1 | − | 1 5 | X | ÷ | 4352 | × | 7 10 |
= | 1 5 | − | 7 217600 | X |
7 43520 | X | = | 1 5 | − | 7 217600 | X |
7 43520 | X | + | 7 217600 | X | = | 1 5 |
21 108800 | X | = | 1 5 |
X | = | 1 5 | ÷ | 21 108800 |
= | 1 5 | × | 108800 21 |
= | 1 | × | 21760 21 |
X | = | 21760 21 |
X | = | 1036.190476 |
