Work: Find the solution of equation 580/(X-40-(X*13%-5)*12%) = 100 .
Question type: Equation
Solution:Original question:
| 580 | ÷ | ( | X | − | 40 | − | ( | X | × | 13 100 | − | 5 | ) | × | 12 100 | ) | = | 100 |
| Multiply both sides of the equation by: | ( | X | − | 40 | − | ( | X | × | 13 100 | − | 5 | ) | × | 12 100 | ) |
| 580 | = | 100 | ( | X | − | 40 | − | ( | X | × | 13 100 | − | 5 | ) | × | 12 100 | ) |
| 580 | = | 100 | X | − | 100 | × | 40 | − | 100 | ( | X | × | 13 100 | − | 5 | ) | × | 12 100 |
| 580 | = | 100 | X | − | 4000 | − | 12 | ( | X | × | 13 100 | − | 5 | ) |
| 580 | = | 100 | X | − | 4000 | − | 12 | X | × | 13 100 | + | 12 | × | 5 |
| 580 | = | 100 | X | − | 4000 | − | 39 25 | X | + | 60 |
| 580 | = | 2461 25 | X | − | 3940 |
Transposition :
| - | 2461 25 | X | = | - | 3940 | − | 580 |
Combine the items on the right of the equation:
| - | 2461 25 | X | = | - | 4520 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 4520 | = | 2461 25 | 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 :
2461 25 | X | = | 4520 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4520 | ÷ | 2461 25 |
| = | 4520 | × | 25 2461 |
We obtained :
| X | = | 113000 2461 |
Convert the result to decimal form :
| X | = | 45.916294 |
