Work: Find the solution of equation （56.85-X）/X = 0.1812 .
Question type: Equation
Solution:Original question:
| ( | 1137 20 | − | X | ) | ÷ | X | = | 453 2500 |
| Multiply both sides of the equation by: | X |
| ( | 1137 20 | − | X | ) | = | 453 2500 | X |
1137 20 | − | X | = | 453 2500 | X |
Transposition :
| - | X | − | 453 2500 | X | = | - | 1137 20 |
Combine the items on the left of the equation:
| - | 2953 2500 | X | = | - | 1137 20 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1137 20 | = | 2953 2500 | 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 :
2953 2500 | X | = | 1137 20 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1137 20 | ÷ | 2953 2500 |
| = | 1137 20 | × | 2500 2953 |
| = | 1137 | × | 125 2953 |
We obtained :
| X | = | 142125 2953 |
Convert the result to decimal form :
| X | = | 48.129021 |
