Work: Find the solution of equation （400-91.58）*165X*365-35.61*365*X*539 = 8350000+10000000X .
Question type: Equation
Solution:Original question:
| ( | 400 | − | 4579 50 | ) | × | 165 | X | × | 365 | − | 3561 100 | × | 365 | X | × | 539 | = | 8350000 | + | 10000000 | X |
| Left side of the equation = | ( | 400 | − | 4579 50 | ) | × | 60225 | X | − | 140114667 20 | X |
| ( | 400 | − | 4579 50 | ) | × | 60225 | X | − | 140114667 20 | X | = | 8350000 | + | 10000000 | X |
| Left side of the equation = | 400 | × | 60225 | X | − | 4579 50 | × | 60225 | X | − | 140114667 20 | X |
| = | 24090000 | X | − | 11030811 2 | X | − | 140114667 20 | X |
| = | 231377223 20 | X |
231377223 20 | X | = | 8350000 | + | 10000000 | X |
Transposition :
231377223 20 | X | − | 10000000 | X | = | 8350000 |
Combine the items on the left of the equation:
31377223 20 | X | = | 8350000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 8350000 | ÷ | 31377223 20 |
| = | 8350000 | × | 20 31377223 |
We obtained :
| X | = | 167000000 31377223 |
Convert the result to decimal form :
| X | = | 5.322332 |
