X | ÷ | 135 | − | ( | 100 | − | X | ) | ÷ | 500 | = | 1 4 |
方程左边 = | 1 135 | X | − | 100 | × | 1 500 | + | X | × | 1 500 |
= | 1 135 | X | − | 1 5 | + | X | × | 1 500 |
= | 127 13500 | X | − | 1 5 |
127 13500 | X | − | 1 5 | = | 1 4 |
127 13500 | X | = | 1 4 | + | 1 5 |
127 13500 | X | = | 9 20 |
X | = | 9 20 | ÷ | 127 13500 |
= | 9 20 | × | 13500 127 |
= | 9 | × | 675 127 |
X | = | 6075 127 |
X | = | 47.834646 |
