Work: Find the solution of equation (2060.1-y)/y = 3% .
Question type: Equation
Solution:Original question:
| ( | 20601 10 | − | y | ) | ÷ | y | = | 3 100 |
| Multiply both sides of the equation by: | y |
| ( | 20601 10 | − | y | ) | = | 3 100 | y |
20601 10 | − | y | = | 3 100 | y |
Transposition :
| - | y | − | 3 100 | y | = | - | 20601 10 |
Combine the items on the left of the equation:
| - | 103 100 | y | = | - | 20601 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
20601 10 | = | 103 100 | y |
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 :
103 100 | y | = | 20601 10 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 20601 10 | ÷ | 103 100 |
| = | 20601 10 | × | 100 103 |
| = | 20601 | × | 10 103 |
We obtained :
| y | = | 206010 103 |
Convert the result to decimal form :
| y | = | 2000.097087 |
