Work: Find the solution of equation X-674.52-（(X-674.52-15000)*10%-2520） = 54945.21 .
Question type: Equation
Solution:Original question:
| X | − | 16863 25 | − | ( | ( | X | − | 16863 25 | − | 15000 | ) | × | 10 100 | − | 2520 | ) | = | 5494521 100 |
| Left side of the equation = | X | − | 16863 25 | − | ( | X | − | 16863 25 | − | 15000 | ) | × | 10 100 | + | 2520 |
| = | X | + | 46137 25 | − | ( | X | − | 16863 25 | − | 15000 | ) | × | 10 100 |
| = | X | + | 46137 25 | − | X | × | 10 100 | + | 16863 25 | × | 10 100 | + | 15000 | × | 10 100 |
| = | X | + | 46137 25 | − | X | × | 10 100 | + | 16863 250 | + | 1500 |
| = | 9 10 | X | + | 853233 250 |
9 10 | X | + | 853233 250 | = | 5494521 100 |
Transposition :
9 10 | X | = | 5494521 100 | − | 853233 250 |
Combine the items on the right of the equation:
9 10 | X | = | 25766139 500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 25766139 500 | ÷ | 9 10 |
| = | 25766139 500 | × | 10 9 |
| = | 8588713 50 | × | 1 3 |
We obtained :
| X | = | 8588713 150 |
Convert the result to decimal form :
| X | = | 57258.086667 |
