Question type: Equation
Solution:Original question:
| ( | ( | 4914679 50 | + | a | + | 843 | + | 8000 | ) | − | 55000 | − | 8430 | − | 843 | ) | × | 10 100 | − | 2520 | = | 51031 50 | + | a |
| Left side of the equation = | ( | 4914679 50 | + | a | + | 843 | + | 8000 | ) | × | 10 100 | − | 55000 | × | 10 100 | − | 8430 | × | 10 100 | − | 843 | × | 10 100 | − | 2520 |
| = | ( | 4914679 50 | + | a | + | 843 | + | 8000 | ) | × | 10 100 | − | 5500 | − | 843 | − | 843 10 | − | 2520 |
| = | ( | 4914679 50 | + | a | + | 843 | + | 8000 | ) | × | 10 100 | − | 89473 10 |
| = | 4914679 50 | × | 10 100 | + | a | × | 10 100 | + | 843 | × | 10 100 | + | 8000 | × | 10 100 | − | 89473 10 |
| = | 4914679 500 | + | a | × | 10 100 | + | 843 10 | + | 800 | − | 89473 10 |
| = | 883179 500 | + | 10 100 | a |
883179 500 | + | 10 100 | a | = | 51031 50 | + | a |
Transposition :
10 100 | a | − | a | = | 51031 50 | − | 883179 500 |
Combine the items on the left of the equation:
| - | 9 10 | a | = | 51031 50 | − | 883179 500 |
Combine the items on the right of the equation:
| - | 9 10 | a | = | - | 372869 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
372869 500 | = | 9 10 | 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 :
9 10 | a | = | 372869 500 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 372869 500 | ÷ | 9 10 |
| = | 372869 500 | × | 10 9 |
| = | 372869 50 | × | 1 9 |
We obtained :
| a | = | 372869 450 |
Convert the result to decimal form :
| a | = | 828.597778 |
