Work: Find the solution of equation 2000 = 16.25*Q*（1-2.654%）-6500-3.75*Q .
Question type: Equation
Solution:Original question:| | 2000 | = | 65 4 | Q | ( | 1 | − | 1327 50000 | ) | − | 6500 | − | 15 4 | Q |
Remove the bracket on the right of the equation:
| Right side of the equation = | 65 4 | Q | × | 1 | − | 65 4 | Q | × | 1327 50000 | − | 6500 | − | 15 4 | Q |
| = | 65 4 | Q | − | 17251 40000 | Q | − | 6500 | − | 15 4 | Q |
The equation is transformed into :
| | 2000 | = | 482749 40000 | Q | − | 6500 |
Transposition :
| | - | 482749 40000 | Q | = | - | 6500 | − | 2000 |
Combine the items on the right of the equation:
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
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 :
The coefficient of the unknown number is reduced to 1 :
We obtained :
This is the solution of the equation.
Convert the result to decimal form :
