Work: Find the solution of equation （82899-2.5X）*11.4/22.4*0.9 = 19390+9X .
Question type: Equation
Solution:Original question:
| ( | 82899 | − | 5 2 | X | ) | × | 57 5 | ÷ | 112 5 | × | 9 10 | = | 19390 | + | 9 | X |
| Left side of the equation = | ( | 82899 | − | 5 2 | X | ) | × | 513 1120 |
| ( | 82899 | − | 5 2 | X | ) | × | 513 1120 | = | 19390 | + | 9 | X |
| Left side of the equation = | 82899 | × | 513 1120 | − | 5 2 | X | × | 513 1120 |
| = | 42527187 1120 | − | 513 448 | X |
42527187 1120 | − | 513 448 | X | = | 19390 | + | 9 | X |
Transposition :
| - | 513 448 | X | − | 9 | X | = | 19390 | − | 42527187 1120 |
Combine the items on the left of the equation:
| - | 4545 448 | X | = | 19390 | − | 42527187 1120 |
Combine the items on the right of the equation:
| - | 4545 448 | X | = | - | 20810387 1120 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
20810387 1120 | = | 4545 448 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
4545 448 | X | = | 20810387 1120 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 20810387 1120 | ÷ | 4545 448 |
| = | 20810387 1120 | × | 448 4545 |
| = | 20810387 5 | × | 2 4545 |
We obtained :
| X | = | 41620774 22725 |
Convert the result to decimal form :
| X | = | 1831.497206 |
