Work: Find the solution of equation X+2.5+18.9+15%*X+（X+15%X）*13% = 1792.19 .
Question type: Equation
Solution:Original question:
| X | + | 5 2 | + | 189 10 | + | 15 100 | X | + | ( | X | + | 15 100 | X | ) | × | 13 100 | = | 179219 100 |
| Left side of the equation = | 23 20 | X | + | 107 5 | + | ( | X | + | 15 100 | X | ) | × | 13 100 |
23 20 | X | + | 107 5 | + | ( | X | + | 15 100 | X | ) | × | 13 100 | = | 179219 100 |
| Left side of the equation = | 23 20 | X | + | 107 5 | + | X | × | 13 100 | + | 15 100 | X | × | 13 100 |
| = | 23 20 | X | + | 107 5 | + | X | × | 13 100 | + | 39 2000 | X |
| = | 2599 2000 | X | + | 107 5 |
2599 2000 | X | + | 107 5 | = | 179219 100 |
Transposition :
2599 2000 | X | = | 179219 100 | − | 107 5 |
Combine the items on the right of the equation:
2599 2000 | X | = | 177079 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 177079 100 | ÷ | 2599 2000 |
| = | 177079 100 | × | 2000 2599 |
| = | 177079 | × | 20 2599 |
We obtained :
| X | = | 3541580 2599 |
Convert the result to decimal form :
| X | = | 1362.670258 |
