Work: Find the solution of equation 90.44/（90.44+x） = 0.03 .
Question type: Equation
Solution:Original question:
2261 25 | ÷ | ( | 2261 25 | + | x | ) | = | 3 100 |
| Multiply both sides of the equation by: | ( | 2261 25 | + | x | ) |
2261 25 | = | 3 100 | ( | 2261 25 | + | x | ) |
2261 25 | = | 3 100 | × | 2261 25 | + | 3 100 | x |
2261 25 | = | 6783 2500 | + | 3 100 | x |
Transposition :
| - | 3 100 | x | = | 6783 2500 | − | 2261 25 |
Combine the items on the right of the equation:
| - | 3 100 | x | = | - | 219317 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
219317 2500 | = | 3 100 | 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 :
3 100 | x | = | 219317 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 219317 2500 | ÷ | 3 100 |
| = | 219317 2500 | × | 100 3 |
| = | 219317 25 | × | 1 3 |
We obtained :
| x | = | 219317 75 |
Convert the result to decimal form :
| x | = | 2924.226667 |
