Work: Find the solution of equation (80.54-x)/x = 130.52 .
Question type: Equation
Solution:Original question:
| ( | 4027 50 | − | x | ) | ÷ | x | = | 3263 25 |
| Multiply both sides of the equation by: | x |
| ( | 4027 50 | − | x | ) | = | 3263 25 | x |
4027 50 | − | x | = | 3263 25 | x |
Transposition :
| - | x | − | 3263 25 | x | = | - | 4027 50 |
Combine the items on the left of the equation:
| - | 3288 25 | x | = | - | 4027 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
4027 50 | = | 3288 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 :
3288 25 | x | = | 4027 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4027 50 | ÷ | 3288 25 |
| = | 4027 50 | × | 25 3288 |
| = | 4027 2 | × | 1 3288 |
We obtained :
| x | = | 4027 6576 |
Convert the result to decimal form :
| x | = | 0.612378 |
