[ 1/1 Equation]
Work: Find the solution of equation 56Q-(580+40Q)-(56Q*13%-5Q)*12% = 0 .
Question type: Equation
Solution:Original question:
| 56 | Q | − | ( | 580 | + | 40 | Q | ) | − | ( | 56 | Q | × | 13 100 | − | 5 | Q | ) | × | 12 100 | = | 0 |
| Left side of the equation = | 56 | Q | − | 580 | − | 40 | Q | − | ( | 56 | Q | × | 13 100 | − | 5 | Q | ) | × | 12 100 |
| = | 16 | Q | − | 580 | − | ( | 56 | Q | × | 13 100 | − | 5 | Q | ) | × | 12 100 |
| = | 16 | Q | − | 580 | − | 56 | Q | × | 13 100 | × | 12 100 | + | 5 | Q | × | 12 100 |
| = | 16 | Q | − | 580 | − | 546 625 | Q | + | 3 5 | Q |
| = | 9829 625 | Q | − | 580 |
9829 625 | Q | − | 580 | = | 0 |
Transposition :
9829 625 | Q | = | 0 | + | 580 |
Combine the items on the right of the equation:
9829 625 | Q | = | 580 |
The coefficient of the unknown number is reduced to 1 :
| Q | = | 580 | ÷ | 9829 625 |
| = | 580 | × | 625 9829 |
We obtained :
| Q | = | 362500 9829 |
Convert the result to decimal form :
| Q | = | 36.880659 |
