Work: Find the solution of equation X-(（X+42839.45-25000-20402.71）*0.03-299.45) = 17800 .
Question type: Equation
Solution:Original question:
| X | − | ( | ( | X | + | 856789 20 | − | 25000 | − | 2040271 100 | ) | × | 3 100 | − | 5989 20 | ) | = | 17800 |
| Left side of the equation = | X | − | ( | X | + | 856789 20 | − | 25000 | − | 2040271 100 | ) | × | 3 100 | + | 5989 20 |
| = | X | − | X | × | 3 100 | − | 856789 20 | × | 3 100 | + | 25000 | × | 3 100 | + | 2040271 100 | × | 3 100 | + | 5989 20 |
| = | X | − | X | × | 3 100 | − | 2570367 2000 | + | 750 | + | 6120813 10000 | + | 5989 20 |
| = | 97 100 | X | + | 1881739 5000 |
97 100 | X | + | 1881739 5000 | = | 17800 |
Transposition :
97 100 | X | = | 17800 | − | 1881739 5000 |
Combine the items on the right of the equation:
97 100 | X | = | 87118261 5000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 87118261 5000 | ÷ | 97 100 |
| = | 87118261 5000 | × | 100 97 |
| = | 87118261 50 | × | 1 97 |
We obtained :
| X | = | 87118261 4850 |
Convert the result to decimal form :
| X | = | 17962.528041 |
