Work: Find the solution of equation [(91713.41+A+843+8000)-55000-6766.8-843]*3% = 1048.4+A .
Question type: Equation
Solution:Original question:
| ( | ( | 9171341 100 | + | A | + | 843 | + | 8000 | ) | − | 55000 | − | 33834 5 | − | 843 | ) | × | 3 100 | = | 5242 5 | + | A |
| Left side of the equation = | ( | 9171341 100 | + | A | + | 843 | + | 8000 | ) | × | 3 100 | − | 55000 | × | 3 100 | − | 33834 5 | × | 3 100 | − | 843 | × | 3 100 |
| = | ( | 9171341 100 | + | A | + | 843 | + | 8000 | ) | × | 3 100 | − | 1650 | − | 50751 250 | − | 2529 100 |
| = | ( | 9171341 100 | + | A | + | 843 | + | 8000 | ) | × | 3 100 | − | 939147 500 |
| = | 9171341 100 | × | 3 100 | + | A | × | 3 100 | + | 843 | × | 3 100 | + | 8000 | × | 3 100 | − | 939147 500 |
| = | 27514023 10000 | + | A | × | 3 100 | + | 2529 100 | + | 240 | − | 939147 500 |
| = | 11383983 10000 | + | 3 100 | A |
11383983 10000 | + | 3 100 | A | = | 5242 5 | + | A |
Transposition :
3 100 | A | − | A | = | 5242 5 | − | 11383983 10000 |
Combine the items on the left of the equation:
| - | 97 100 | A | = | 5242 5 | − | 11383983 10000 |
Combine the items on the right of the equation:
| - | 97 100 | A | = | - | 899983 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
899983 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 | = | 899983 10000 |
The coefficient of the unknown number is reduced to 1 :
| A | = | 899983 10000 | ÷ | 97 100 |
| = | 899983 10000 | × | 100 97 |
| = | 899983 100 | × | 1 97 |
We obtained :
| A | = | 899983 9700 |
Convert the result to decimal form :
| A | = | 92.781753 |
