Work: Find the solution of equation （227.76-X）/X = 10.5% .
Question type: Equation
Solution:Original question:
| ( | 5694 25 | − | X | ) | ÷ | X | = | 21 200 |
| Multiply both sides of the equation by: | X |
| ( | 5694 25 | − | X | ) | = | 21 200 | X |
5694 25 | − | X | = | 21 200 | X |
Transposition :
| - | X | − | 21 200 | X | = | - | 5694 25 |
Combine the items on the left of the equation:
| - | 221 200 | X | = | - | 5694 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5694 25 | = | 221 200 | 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 :
221 200 | X | = | 5694 25 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 5694 25 | ÷ | 221 200 |
| = | 5694 25 | × | 200 221 |
| = | 438 | × | 8 17 |
We obtained :
| X | = | 3504 17 |
Convert the result to decimal form :
| X | = | 206.117647 |
