X | ÷ | 2352 | × | 7 10 | = | 1 5 | ( | 1 | − | X | ÷ | 2352 | × | 7 10 | ) |
方程左边 = | X | × | 1 3360 |
1 3360 | X | = | 1 5 | ( | 1 | − | X | ÷ | 2352 | × | 7 10 | ) |
方程右边 = | 1 5 | × | 1 | − | 1 5 | X | ÷ | 2352 | × | 7 10 |
= | 1 5 | − | 1 16800 | X |
1 3360 | X | = | 1 5 | − | 1 16800 | X |
1 3360 | X | + | 1 16800 | X | = | 1 5 |
1 2800 | X | = | 1 5 |
X | = | 1 5 | ÷ | 1 2800 |
= | 1 5 | × | 2800 |
= | 1 | × | 560 |
X | = | 560 |
