Work: Find the solution of equation （27000-3.88x）÷(25.99x+4.33x) = 3.83% .
Question type: Equation
Solution:Original question:
| ( | 27000 | − | 97 25 | x | ) | ÷ | ( | 2599 100 | x | + | 433 100 | x | ) | = | 383 10000 |
| Multiply both sides of the equation by: | ( | 2599 100 | x | + | 433 100 | x | ) |
| ( | 27000 | − | 97 25 | x | ) | = | 383 10000 | ( | 2599 100 | x | + | 433 100 | x | ) |
| 27000 | − | 97 25 | x | = | 383 10000 | ( | 2599 100 | x | + | 433 100 | x | ) |
| 27000 | − | 97 25 | x | = | 383 10000 | × | 2599 100 | x | + | 383 10000 | × | 433 100 | x |
| 27000 | − | 97 25 | x | = | 995417 1000000 | x | + | 165839 1000000 | x |
| 27000 | − | 97 25 | x | = | 145157 125000 | x |
Transposition :
| - | 97 25 | x | − | 145157 125000 | x | = | - | 27000 |
Combine the items on the left of the equation:
| - | 630157 125000 | x | = | - | 27000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 27000 | = | 630157 125000 | 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 :
630157 125000 | x | = | 27000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 27000 | ÷ | 630157 125000 |
| = | 27000 | × | 125000 630157 |
We obtained :
| x | = | 3375000000 630157 |
Convert the result to decimal form :
| x | = | 5355.808156 |
