Work: Find the solution of equation [(60927.81+a+10000)-35000]*3% = 927.82+a .
Question type: Equation
Solution:Original question:
| ( | ( | 6092781 100 | + | a | + | 10000 | ) | − | 35000 | ) | × | 3 100 | = | 46391 50 | + | a |
| Left side of the equation = | ( | 6092781 100 | + | a | + | 10000 | ) | × | 3 100 | − | 35000 | × | 3 100 |
| = | ( | 6092781 100 | + | a | + | 10000 | ) | × | 3 100 | − | 1050 |
| = | 6092781 100 | × | 3 100 | + | a | × | 3 100 | + | 10000 | × | 3 100 | − | 1050 |
| = | 18278343 10000 | + | a | × | 3 100 | + | 300 | − | 1050 |
| = | 10778343 10000 | + | 3 100 | a |
10778343 10000 | + | 3 100 | a | = | 46391 50 | + | a |
Transposition :
3 100 | a | − | a | = | 46391 50 | − | 10778343 10000 |
Combine the items on the left of the equation:
| - | 97 100 | a | = | 46391 50 | − | 10778343 10000 |
Combine the items on the right of the equation:
| - | 97 100 | a | = | - | 1500143 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1500143 10000 | = | 97 100 | 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 :
97 100 | a | = | 1500143 10000 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 1500143 10000 | ÷ | 97 100 |
| = | 1500143 10000 | × | 100 97 |
| = | 1500143 100 | × | 1 97 |
We obtained :
| a | = | 1500143 9700 |
Convert the result to decimal form :
| a | = | 154.653918 |
