Work: Find the solution of equation X+0.002*500+0.015X+0.1X+(X+0.1X)*0.13 = 717.1 .
Question type: Equation
Solution:Original question:
| X | + | 1 500 | × | 500 | + | 3 200 | X | + | 1 10 | X | + | ( | X | + | 1 10 | X | ) | × | 13 100 | = | 7171 10 |
| Left side of the equation = | X | + | 1 | + | 3 200 | X | + | 1 10 | X | + | ( | X | + | 1 10 | X | ) | × | 13 100 |
| = | 223 200 | X | + | 1 | + | ( | X | + | 1 10 | X | ) | × | 13 100 |
223 200 | X | + | 1 | + | ( | X | + | 1 10 | X | ) | × | 13 100 | = | 7171 10 |
| Left side of the equation = | 223 200 | X | + | 1 | + | X | × | 13 100 | + | 1 10 | X | × | 13 100 |
| = | 223 200 | X | + | 1 | + | X | × | 13 100 | + | 13 1000 | X |
| = | 629 500 | X | + | 1 |
629 500 | X | + | 1 | = | 7171 10 |
Transposition :
629 500 | X | = | 7171 10 | − | 1 |
Combine the items on the right of the equation:
629 500 | X | = | 7161 10 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 7161 10 | ÷ | 629 500 |
| = | 7161 10 | × | 500 629 |
| = | 7161 | × | 50 629 |
We obtained :
| X | = | 358050 629 |
Convert the result to decimal form :
| X | = | 569.236884 |
