Work: Find the solution of equation [(40982.02+a+843+8000)-30000-4215]*3% = 353.01+a .
Question type: Equation
Solution:Original question:
| ( | ( | 2049101 50 | + | a | + | 843 | + | 8000 | ) | − | 30000 | − | 4215 | ) | × | 3 100 | = | 35301 100 | + | a |
| Left side of the equation = | ( | 2049101 50 | + | a | + | 843 | + | 8000 | ) | × | 3 100 | − | 30000 | × | 3 100 | − | 4215 | × | 3 100 |
| = | ( | 2049101 50 | + | a | + | 843 | + | 8000 | ) | × | 3 100 | − | 900 | − | 2529 20 |
| = | ( | 2049101 50 | + | a | + | 843 | + | 8000 | ) | × | 3 100 | − | 20529 20 |
| = | 2049101 50 | × | 3 100 | + | a | × | 3 100 | + | 843 | × | 3 100 | + | 8000 | × | 3 100 | − | 20529 20 |
| = | 6147303 5000 | + | a | × | 3 100 | + | 2529 100 | + | 240 | − | 20529 20 |
| = | 2341503 5000 | + | 3 100 | a |
2341503 5000 | + | 3 100 | a | = | 35301 100 | + | a |
Transposition :
3 100 | a | − | a | = | 35301 100 | − | 2341503 5000 |
Combine the items on the left of the equation:
| - | 97 100 | a | = | 35301 100 | − | 2341503 5000 |
Combine the items on the right of the equation:
| - | 97 100 | a | = | - | 576453 5000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
576453 5000 | = | 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 | = | 576453 5000 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 576453 5000 | ÷ | 97 100 |
| = | 576453 5000 | × | 100 97 |
| = | 576453 50 | × | 1 97 |
We obtained :
| a | = | 576453 4850 |
Convert the result to decimal form :
| a | = | 118.856289 |
