Work: Find the solution of equation (177-x)/x*100 = 92.3913043 .
Question type: Equation
Solution:Original question:
| ( | 177 | − | x | ) | ÷ | x | × | 100 | = | 923913043 10000000 |
| Multiply both sides of the equation by: | x |
| ( | 177 | − | x | ) | × | 100 | = | 923913043 10000000 | x |
| 177 | × | 100 | − | x | × | 100 | = | 923913043 10000000 | x |
| 17700 | − | x | × | 100 | = | 923913043 10000000 | x |
Transposition :
| - | 100 | x | − | 923913043 10000000 | x | = | - | 17700 |
Combine the items on the left of the equation:
| - | 1923913043 10000000 | x | = | - | 17700 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 17700 | = | 1923913043 10000000 | 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 :
1923913043 10000000 | x | = | 17700 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 17700 | ÷ | 1923913043 10000000 |
| = | 17700 | × | 10000000 1923913043 |
We obtained :
| x | = | 177000000000 1923913043 |
