Work: Find the solution of equation 1918.24-a-a*(1/1000) = 18.24 .
Question type: Equation
Solution:Original question:
47956 25 | − | a | − | a | ( | 1 | ÷ | 1000 | ) | = | 456 25 |
| Left side of the equation = | 47956 25 | − | a | − | a | × | 1 | ÷ | 1000 |
| = | 47956 25 | − | a | − | a | × | 1 1000 |
| = | 47956 25 | − | 1001 1000 | a |
47956 25 | − | 1001 1000 | a | = | 456 25 |
Transposition :
| - | 1001 1000 | a | = | 456 25 | − | 47956 25 |
Combine the items on the right of the equation:
| - | 1001 1000 | a | = | - | 1900 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 1900 | = | 1001 1000 | 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 :
1001 1000 | a | = | 1900 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 1900 | ÷ | 1001 1000 |
| = | 1900 | × | 1000 1001 |
We obtained :
| a | = | 1900000 1001 |
Convert the result to decimal form :
| a | = | 1898.101898 |
