Work: Find the solution of equation 0.641*85175-0.641*X = 66679.26-X .
Question type: Equation
Solution:Original question:
641 1000 | × | 85175 | − | 641 1000 | X | = | 3333963 50 | − | X |
| Left side of the equation = | 2183887 40 | − | 641 1000 | X |
2183887 40 | − | 641 1000 | X | = | 3333963 50 | − | X |
Transposition :
| - | 641 1000 | X | + | X | = | 3333963 50 | − | 2183887 40 |
Combine the items on the left of the equation:
| - | - | 359 1000 | X | = | 3333963 50 | − | 2183887 40 |
Combine the items on the right of the equation:
| - | - | 359 1000 | X | = | 2416417 200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 2416417 200 | = | - | 359 1000 | 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 :
| - | 359 1000 | X | = | - | 2416417 200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2416417 200 | ÷ | 359 1000 |
| = | 2416417 200 | × | 1000 359 |
| = | 2416417 | × | 5 359 |
We obtained :
| X | = | 12082085 359 |
Convert the result to decimal form :
| X | = | 33654.832869 |
