Work: Find the solution of equation x+191740+x*0.05+(x+191740+x*0.05)*0.09 = 2570000 .
Question type: Equation
Solution:Original question:
| x | + | 191740 | + | x | × | 1 20 | + | ( | x | + | 191740 | + | x | × | 1 20 | ) | × | 9 100 | = | 2570000 |
| Left side of the equation = | 21 20 | x | + | 191740 | + | ( | x | + | 191740 | + | x | × | 1 20 | ) | × | 9 100 |
21 20 | x | + | 191740 | + | ( | x | + | 191740 | + | x | × | 1 20 | ) | × | 9 100 | = | 2570000 |
| Left side of the equation = | 21 20 | x | + | 191740 | + | x | × | 9 100 | + | 191740 | × | 9 100 | + | x | × | 1 20 | × | 9 100 |
| = | 21 20 | x | + | 191740 | + | x | × | 9 100 | + | 86283 5 | + | x | × | 9 2000 |
| = | 2289 2000 | x | + | 1044983 5 |
2289 2000 | x | + | 1044983 5 | = | 2570000 |
Transposition :
2289 2000 | x | = | 2570000 | − | 1044983 5 |
Combine the items on the right of the equation:
2289 2000 | x | = | 11805017 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11805017 5 | ÷ | 2289 2000 |
| = | 11805017 5 | × | 2000 2289 |
| = | 1686431 | × | 400 327 |
We obtained :
| x | = | 674572400 327 |
Convert the result to decimal form :
| x | = | 2062912.538226 |
