Work: Find the solution of equation 36Q-(2239.5+12.45Q)-(36Q*13%-2.75Q)*12% = 0 .
Question type: Equation
Solution:Original question:
| 36 | Q | − | ( | 4479 2 | + | 249 20 | Q | ) | − | ( | 36 | Q | × | 13 100 | − | 11 4 | Q | ) | × | 12 100 | = | 0 |
| Left side of the equation = | 36 | Q | − | 4479 2 | − | 249 20 | Q | − | ( | 36 | Q | × | 13 100 | − | 11 4 | Q | ) | × | 12 100 |
| = | 471 20 | Q | − | 4479 2 | − | ( | 36 | Q | × | 13 100 | − | 11 4 | Q | ) | × | 12 100 |
| = | 471 20 | Q | − | 4479 2 | − | 36 | Q | × | 13 100 | × | 12 100 | + | 11 4 | Q | × | 12 100 |
| = | 471 20 | Q | − | 4479 2 | − | 351 625 | Q | + | 33 100 | Q |
| = | 14574 625 | Q | − | 4479 2 |
14574 625 | Q | − | 4479 2 | = | 0 |
Transposition :
14574 625 | Q | = | 0 | + | 4479 2 |
Combine the items on the right of the equation:
14574 625 | Q | = | 4479 2 |
The coefficient of the unknown number is reduced to 1 :
| Q | = | 4479 2 | ÷ | 14574 625 |
| = | 4479 2 | × | 625 14574 |
| = | 1493 2 | × | 625 4858 |
We obtained :
| Q | = | 933125 9716 |
Convert the result to decimal form :
| Q | = | 96.040037 |
