( | 2300 | + | 85 | + | X | ) | × | 61 1000 | = | ( | 360 | ÷ | 180 | ) | X |
方程左边 = | 2300 | × | 61 1000 | + | 85 | × | 61 1000 | + | X | × | 61 1000 |
= | 1403 10 | + | 1037 200 | + | X | × | 61 1000 |
= | 29097 200 | + | 61 1000 | X |
29097 200 | + | 61 1000 | X | = | ( | 360 | ÷ | 180 | ) | X |
方程右边 = | 360 | ÷ | 180 | × | X |
= | 2 | X |
29097 200 | + | 61 1000 | X | = | 2 | X |
61 1000 | X | − | 2 | X | = | - | 29097 200 |
- | 1939 1000 | X | = | - | 29097 200 |
29097 200 | = | 1939 1000 | X |
1939 1000 | X | = | 29097 200 |
X | = | 29097 200 | ÷ | 1939 1000 |
= | 29097 200 | × | 1000 1939 |
= | 29097 | × | 5 1939 |
X | = | 145485 1939 |
X | = | 75.030944 |
