Work: Find the solution of equation X-0.02X-(X/1.09*0.09*1.12)-X/1.09*0.8-17.68 = 0 .
Question type: Equation
Solution:Original question:
| X | − | 1 50 | X | − | ( | X | ÷ | 109 100 | × | 9 100 | × | 28 25 | ) | − | X | ÷ | 109 100 | × | 4 5 | − | 442 25 | = | 0 |
| Left side of the equation = | X | − | 1 50 | X | − | ( | X | ÷ | 109 100 | × | 9 100 | × | 28 25 | ) | − | X | × | 80 109 | − | 442 25 |
| = | 1341 5450 | X | − | ( | X | ÷ | 109 100 | × | 9 100 | × | 28 25 | ) | − | 442 25 |
1341 5450 | X | − | ( | X | ÷ | 109 100 | × | 9 100 | × | 28 25 | ) | − | 442 25 | = | 0 |
| Left side of the equation = | 1341 5450 | X | − | X | ÷ | 109 100 | × | 9 100 | × | 28 25 | − | 442 25 |
| = | 1341 5450 | X | − | X | × | 252 2725 | − | 442 25 |
| = | 837 5450 | X | − | 442 25 |
837 5450 | X | − | 442 25 | = | 0 |
Transposition :
837 5450 | X | = | 0 | + | 442 25 |
Combine the items on the right of the equation:
837 5450 | X | = | 442 25 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 442 25 | ÷ | 837 5450 |
| = | 442 25 | × | 5450 837 |
| = | 442 | × | 218 837 |
We obtained :
| X | = | 96356 837 |
Convert the result to decimal form :
| X | = | 115.120669 |
