Work: Find the solution of equation (5230.7-y)/y = 2.6% .
Question type: Equation
Solution:Original question:
| ( | 52307 10 | − | y | ) | ÷ | y | = | 13 500 |
| Multiply both sides of the equation by: | y |
| ( | 52307 10 | − | y | ) | = | 13 500 | y |
52307 10 | − | y | = | 13 500 | y |
Transposition :
| - | y | − | 13 500 | y | = | - | 52307 10 |
Combine the items on the left of the equation:
| - | 513 500 | y | = | - | 52307 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
52307 10 | = | 513 500 | 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 :
513 500 | y | = | 52307 10 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 52307 10 | ÷ | 513 500 |
| = | 52307 10 | × | 500 513 |
| = | 2753 | × | 50 27 |
We obtained :
| y | = | 137650 27 |
Convert the result to decimal form :
| y | = | 5098.148148 |
