Work: Find the solution of equation X/87-20/1900-20/167 = 0.00167(x+40） .
Question type: Equation
Solution:Original question:
| X | ÷ | 87 | − | 20 | ÷ | 1900 | − | 20 | ÷ | 167 | = | 167 100000 | ( | X | + | 40 | ) |
| Left side of the equation = | X | × | 1 87 | − | 1 95 | − | 20 167 |
| = | 1 87 | X | − | 2067 15865 |
1 87 | X | − | 2067 15865 | = | 167 100000 | ( | X | + | 40 | ) |
| Right side of the equation = | 167 100000 | X | + | 167 100000 | × | 40 |
| = | 167 100000 | X | + | 167 2500 |
1 87 | X | − | 2067 15865 | = | 167 100000 | X | + | 167 2500 |
Transposition :
1 87 | X | − | 167 100000 | X | = | 167 2500 | + | 2067 15865 |
Combine the items on the left of the equation:
85471 8700000 | X | = | 167 2500 | + | 2067 15865 |
Combine the items on the right of the equation:
85471 8700000 | X | = | 1563391 7932500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1563391 7932500 | ÷ | 85471 8700000 |
| = | 1563391 7932500 | × | 8700000 85471 |
| = | 1563391 3173 | × | 3480 85471 |
We obtained :
| X | = | 5440600680 271199483 |
Convert the result to decimal form :
| X | = | 20.06125 |
