Work: Find the solution of equation 70*Q-(20*Q+300+516.48)-(70*13%*Q-2Q)*10% = 464 .
Question type: Equation
Solution:Original question:
| 70 | Q | − | ( | 20 | Q | + | 300 | + | 12912 25 | ) | − | ( | 70 | × | 13 100 | Q | − | 2 | Q | ) | × | 10 100 | = | 464 |
| Left side of the equation = | 70 | Q | − | 20 | Q | − | 300 | − | 12912 25 | − | ( | 70 | × | 13 100 | Q | − | 2 | Q | ) | × | 10 100 |
| = | 50 | Q | − | 20412 25 | − | ( | 70 | × | 13 100 | Q | − | 2 | Q | ) | × | 10 100 |
| = | 50 | Q | − | 20412 25 | − | 70 | × | 13 100 | Q | × | 10 100 | + | 2 | Q | × | 10 100 |
| = | 50 | Q | − | 20412 25 | − | 91 100 | Q | + | 1 5 | Q |
| = | 4929 100 | Q | − | 20412 25 |
4929 100 | Q | − | 20412 25 | = | 464 |
Transposition :
4929 100 | Q | = | 464 | + | 20412 25 |
Combine the items on the right of the equation:
4929 100 | Q | = | 32012 25 |
The coefficient of the unknown number is reduced to 1 :
| Q | = | 32012 25 | ÷ | 4929 100 |
| = | 32012 25 | × | 100 4929 |
| = | 604 | × | 4 93 |
We obtained :
| Q | = | 2416 93 |
Convert the result to decimal form :
| Q | = | 25.978495 |
