Work: Find the solution of equation (x-12.3%)/(21.4%-x) = 1.04/3.2 .
Question type: Equation
Solution:Original question:
| ( | x | − | 123 1000 | ) | ÷ | ( | 107 500 | − | x | ) | = | 26 25 | ÷ | 16 5 |
| Multiply both sides of the equation by: | ( | 107 500 | − | x | ) |
| ( | x | − | 123 1000 | ) | = | 26 25 | ÷ | 16 5 | × | ( | 107 500 | − | x | ) |
| x | − | 123 1000 | = | 26 25 | ÷ | 16 5 | × | ( | 107 500 | − | x | ) |
| x | − | 123 1000 | = | 26 25 | ÷ | 16 5 | × | 107 500 | − | 26 25 | ÷ | 16 5 | × | x |
| x | − | 123 1000 | = | 1391 20000 | − | 13 40 | x |
Transposition :
| x | + | 13 40 | x | = | 1391 20000 | + | 123 1000 |
Combine the items on the left of the equation:
53 40 | x | = | 1391 20000 | + | 123 1000 |
Combine the items on the right of the equation:
53 40 | x | = | 3851 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3851 20000 | ÷ | 53 40 |
| = | 3851 20000 | × | 40 53 |
| = | 3851 500 | × | 1 53 |
We obtained :
| x | = | 3851 26500 |
Convert the result to decimal form :
| x | = | 0.145321 |
