Work: Find the solution of equation （93474-1.5X）*9.2/21.2*0.9 = 16802+7X .
Question type: Equation
Solution:Original question:
| ( | 93474 | − | 3 2 | X | ) | × | 46 5 | ÷ | 106 5 | × | 9 10 | = | 16802 | + | 7 | X |
| Left side of the equation = | ( | 93474 | − | 3 2 | X | ) | × | 207 530 |
| ( | 93474 | − | 3 2 | X | ) | × | 207 530 | = | 16802 | + | 7 | X |
| Left side of the equation = | 93474 | × | 207 530 | − | 3 2 | X | × | 207 530 |
| = | 9674559 265 | − | 621 1060 | X |
9674559 265 | − | 621 1060 | X | = | 16802 | + | 7 | X |
Transposition :
| - | 621 1060 | X | − | 7 | X | = | 16802 | − | 9674559 265 |
Combine the items on the left of the equation:
| - | 8041 1060 | X | = | 16802 | − | 9674559 265 |
Combine the items on the right of the equation:
| - | 8041 1060 | X | = | - | 5222029 265 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5222029 265 | = | 8041 1060 | 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 :
8041 1060 | X | = | 5222029 265 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 5222029 265 | ÷ | 8041 1060 |
| = | 5222029 265 | × | 1060 8041 |
| = | 5222029 | × | 4 8041 |
We obtained :
| X | = | 20888116 8041 |
Convert the result to decimal form :
| X | = | 2597.701281 |
