Work: Find the solution of equation （(3643-X-6140)/6140)*0.5 = ((1678+65+X)-3716)/3716 .
Question type: Equation
Solution:Original question:
| ( | ( | 3643 | − | X | − | 6140 | ) | ÷ | 6140 | ) | × | 1 2 | = | ( | ( | 1678 | + | 65 | + | X | ) | − | 3716 | ) | ÷ | 3716 |
| Left side of the equation = | ( | 3643 | − | X | − | 6140 | ) | ÷ | 6140 | × | 1 2 |
| = | ( | 3643 | − | X | − | 6140 | ) | × | 1 12280 |
| = | 3643 | × | 1 12280 | − | X | × | 1 12280 | − | 6140 | × | 1 12280 |
| = | 3643 12280 | − | X | × | 1 12280 | − | 1 2 |
| = | - | 2497 12280 | − | 1 12280 | X |
| - | 2497 12280 | − | 1 12280 | X | = | ( | ( | 1678 | + | 65 | + | X | ) | − | 3716 | ) | ÷ | 3716 |
| Right side of the equation = | ( | 1678 | + | 65 | + | X | ) | × | 1 3716 | − | 3716 | × | 1 3716 |
| = | ( | 1678 | + | 65 | + | X | ) | × | 1 3716 | − | 1 |
| = | 1678 | × | 1 3716 | + | 65 | × | 1 3716 | + | X | × | 1 3716 | − | 1 |
| = | 839 1858 | + | 65 3716 | + | X | × | 1 3716 | − | 1 |
| = | - | 1973 3716 | + | 1 3716 | X |
| - | 2497 12280 | − | 1 12280 | X | = | - | 1973 3716 | + | 1 3716 | X |
Transposition :
| - | 1 12280 | X | − | 1 3716 | X | = | - | 1973 3716 | + | 2497 12280 |
Combine the items on the left of the equation:
| - | 3999 11408120 | X | = | - | 1973 3716 | + | 2497 12280 |
Combine the items on the right of the equation:
| - | 3999 11408120 | X | = | - | 3737397 11408120 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3737397 11408120 | = | 3999 11408120 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
3999 11408120 | X | = | 3737397 11408120 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 3737397 11408120 | ÷ | 3999 11408120 |
| = | 3737397 11408120 | × | 11408120 3999 |
| = | 1245799 929 | × | 929 1333 |
We obtained :
| X | = | 1157347271 1238357 |
By reducing fraction, we can get:
| X | = | 1245799 1333 |
Convert the result to decimal form :
| X | = | 934.582896 |
