Work: Find the solution of equation (x-16.24)/x = 80% .
Question type: Equation
Solution:Original question:
| ( | x | − | 406 25 | ) | ÷ | x | = | 80 100 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 406 25 | ) | = | 80 100 | x |
| x | − | 406 25 | = | 80 100 | x |
Transposition :
| x | − | 80 100 | x | = | 406 25 |
Combine the items on the left of the equation:
1 5 | x | = | 406 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 406 25 | ÷ | 1 5 |
| = | 406 25 | × | 5 |
| = | 406 5 | × | 1 |
We obtained :
| x | = | 406 5 |
Convert the result to decimal form :
| x | = | 81.2 |
