Work: Find the solution of equation 450Q-(70+240Q+171+69.02)-(450Q*0.13-15Q-30.4)*0.12 = 0 .
Question type: Equation
Solution:Original question:
| 450 | Q | − | ( | 70 | + | 240 | Q | + | 171 | + | 3451 50 | ) | − | ( | 450 | Q | × | 13 100 | − | 15 | Q | − | 152 5 | ) | × | 3 25 | = | 0 |
| Left side of the equation = | 450 | Q | − | 70 | − | 240 | Q | − | 171 | − | 3451 50 | − | ( | 450 | Q | × | 13 100 | − | 15 | Q | − | 152 5 | ) | × | 3 25 |
| = | 210 | Q | − | 15501 50 | − | ( | 450 | Q | × | 13 100 | − | 15 | Q | − | 152 5 | ) | × | 3 25 |
| = | 210 | Q | − | 15501 50 | − | 450 | Q | × | 13 100 | × | 3 25 | + | 15 | Q | × | 3 25 | + | 152 5 | × | 3 25 |
| = | 210 | Q | − | 15501 50 | − | 351 50 | Q | + | 9 5 | Q | + | 456 125 |
| = | 10239 50 | Q | − | 76593 250 |
10239 50 | Q | − | 76593 250 | = | 0 |
Transposition :
10239 50 | Q | = | 0 | + | 76593 250 |
Combine the items on the right of the equation:
10239 50 | Q | = | 76593 250 |
The coefficient of the unknown number is reduced to 1 :
| Q | = | 76593 250 | ÷ | 10239 50 |
| = | 76593 250 | × | 50 10239 |
| = | 25531 5 | × | 1 3413 |
We obtained :
| Q | = | 25531 17065 |
Convert the result to decimal form :
| Q | = | 1.496103 |
