Work: Find the solution of equation (1091.6/1.09*0.09*1.12-(1091.6/1.09-x)*0.06) = x .
Question type: Equation
Solution:Original question:
| ( | 5458 5 | ÷ | 109 100 | × | 9 100 | × | 28 25 | − | ( | 5458 5 | ÷ | 109 100 | − | x | ) | × | 3 50 | ) | = | x |
| Left side of the equation = | 5458 5 | ÷ | 109 100 | × | 9 100 | × | 28 25 | − | ( | 5458 5 | ÷ | 109 100 | − | x | ) | × | 3 50 |
| = | 1375416 13625 | − | ( | 5458 5 | ÷ | 109 100 | − | x | ) | × | 3 50 |
| = | 1375416 13625 | − | 5458 5 | ÷ | 109 100 | × | 3 50 | + | x | × | 3 50 |
| = | 1375416 13625 | − | 32748 545 | + | x | × | 3 50 |
| = | 556716 13625 | + | 3 50 | x |
556716 13625 | + | 3 50 | x | = | x |
Transposition :
3 50 | x | − | x | = | - | 556716 13625 |
Combine the items on the left of the equation:
| - | 47 50 | x | = | - | 556716 13625 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
556716 13625 | = | 47 50 | x |
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 :
47 50 | x | = | 556716 13625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 556716 13625 | ÷ | 47 50 |
| = | 556716 13625 | × | 50 47 |
| = | 556716 545 | × | 2 47 |
We obtained :
| x | = | 1113432 25615 |
Convert the result to decimal form :
| x | = | 43.467968 |
