2800 | ÷ | 126 | − | X | ÷ | 1000 | = | 381 100000 | ( | 2800 | + | X | ) |
方程左边 = | 200 9 | − | X | × | 1 1000 |
200 9 | − | 1 1000 | X | = | 381 100000 | ( | 2800 | + | X | ) |
方程右边 = | 381 100000 | × | 2800 | + | 381 100000 | X |
= | 2667 250 | + | 381 100000 | X |
200 9 | − | 1 1000 | X | = | 2667 250 | + | 381 100000 | X |
- | 1 1000 | X | − | 381 100000 | X | = | 2667 250 | − | 200 9 |
- | 481 100000 | X | = | 2667 250 | − | 200 9 |
- | 481 100000 | X | = | - | 25997 2250 |
25997 2250 | = | 481 100000 | X |
481 100000 | X | = | 25997 2250 |
X | = | 25997 2250 | ÷ | 481 100000 |
= | 25997 2250 | × | 100000 481 |
= | 25997 9 | × | 400 481 |
X | = | 10398800 4329 |
X | = | 2402.125202 |
