( | 61 50 | − | X | ) | ÷ | 230 | = | ( | 37 25 | − | X | ) | ÷ | 306 |
方程左边 = | 61 50 | × | 1 230 | − | X | × | 1 230 |
= | 61 11500 | − | X | × | 1 230 |
61 11500 | − | 1 230 | X | = | ( | 37 25 | − | X | ) | ÷ | 306 |
方程右边 = | 37 25 | × | 1 306 | − | X | × | 1 306 |
= | 37 7650 | − | X | × | 1 306 |
61 11500 | − | 1 230 | X | = | 37 7650 | − | 1 306 | X |
- | 1 230 | X | + | 1 306 | X | = | 37 7650 | − | 61 11500 |
- | 19 17595 | X | = | 37 7650 | − | 61 11500 |
- | 19 17595 | X | = | - | 823 1759500 |
823 1759500 | = | 19 17595 | X |
19 17595 | X | = | 823 1759500 |
X | = | 823 1759500 | ÷ | 19 17595 |
= | 823 1759500 | × | 17595 19 |
= | 823 100 | × | 1 19 |
X | = | 823 1900 |
X | = | 0.433158 |
