Work: Find the solution of equation （x-7920）/x = 39.38% .
Question type: Equation
Solution:Original question:
| ( | x | − | 7920 | ) | ÷ | x | = | 1969 5000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 7920 | ) | = | 1969 5000 | x |
| x | − | 7920 | = | 1969 5000 | x |
Transposition :
| x | − | 1969 5000 | x | = | 7920 |
Combine the items on the left of the equation:
3031 5000 | x | = | 7920 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7920 | ÷ | 3031 5000 |
| = | 7920 | × | 5000 3031 |
We obtained :
| x | = | 39600000 3031 |
Convert the result to decimal form :
| x | = | 13064.995051 |
