Work: Find the solution of equation 14151×（0.14669-1.01752Y）＋14402Y = 2076.25 .
Question type: Equation
Solution:Original question:
| 14151 | ( | 14669 100000 | − | 12719 12500 | Y | ) | + | 14402 | Y | = | 8305 4 |
| Left side of the equation = | 14151 | × | 14669 100000 | − | 14151 | × | 12719 12500 | Y | + | 14402 | Y |
| = | 207581019 100000 | − | 179986569 12500 | Y | + | 14402 | Y |
| = | 207581019 100000 | + | 38431 12500 | Y |
207581019 100000 | + | 38431 12500 | Y | = | 8305 4 |
Transposition :
38431 12500 | Y | = | 8305 4 | − | 207581019 100000 |
Combine the items on the right of the equation:
38431 12500 | Y | = | 43981 100000 |
The coefficient of the unknown number is reduced to 1 :
| Y | = | 43981 100000 | ÷ | 38431 12500 |
| = | 43981 100000 | × | 12500 38431 |
| = | 43981 8 | × | 1 38431 |
We obtained :
| Y | = | 43981 307448 |
Convert the result to decimal form :
| Y | = | 0.143052 |
