Work: Find the solution of equation 1/0.0174×（1/x-1/1.32） = 250 .
Question type: Equation
Solution:Original question:
| 1 | ÷ | 87 5000 | × | ( | 1 | ÷ | x | − | 1 | ÷ | 33 25 | ) | = | 250 |
| 1 | ÷ | 87 5000 | × | 1 | ÷ | x | − | 1 | ÷ | 87 5000 | × | 1 | ÷ | 33 25 | = | 250 |
5000 87 | ÷ | x | − | 125000 2871 | = | 250 |
| Multiply both sides of the equation by: | x |
5000 87 | − | 125000 2871 | x | = | 250 | x |
Transposition :
| - | 125000 2871 | x | − | 250 | x | = | - | 5000 87 |
Combine the items on the left of the equation:
| - | 842750 2871 | x | = | - | 5000 87 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5000 87 | = | 842750 2871 | 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 :
842750 2871 | x | = | 5000 87 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5000 87 | ÷ | 842750 2871 |
| = | 5000 87 | × | 2871 842750 |
| = | 20 | × | 33 3371 |
We obtained :
| x | = | 660 3371 |
Convert the result to decimal form :
| x | = | 0.195788 |
