[ 1/1 Equation]
Work: Find the solution of equation (5268220-a)/a = 1.66 .
Question type: Equation
Solution:Original question:
| ( | 5268220 | − | a | ) | ÷ | a | = | 83 50 |
| Multiply both sides of the equation by: | a |
| ( | 5268220 | − | a | ) | = | 83 50 | a |
| 5268220 | − | a | = | 83 50 | a |
Transposition :
| - | a | − | 83 50 | a | = | - | 5268220 |
Combine the items on the left of the equation:
| - | 133 50 | a | = | - | 5268220 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 5268220 | = | 133 50 | a |
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 :
133 50 | a | = | 5268220 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 5268220 | ÷ | 133 50 |
| = | 5268220 | × | 50 133 |
We obtained :
| a | = | 263411000 133 |
Convert the result to decimal form :
| a | = | 1980533.834586 |
