Work: Find the solution of equation 0.137Z-3+0.119Z-2+0.269Z-1－0.019 = 0.1678 .
Question type: Equation
Solution:Original question:
137 1000 | Z | − | 3 | + | 119 1000 | Z | − | 2 | + | 269 1000 | Z | − | 1 | − | 19 1000 | = | 839 5000 |
| Left side of the equation = | 21 40 | Z | − | 6019 1000 |
21 40 | Z | − | 6019 1000 | = | 839 5000 |
Transposition :
21 40 | Z | = | 839 5000 | + | 6019 1000 |
Combine the items on the right of the equation:
21 40 | Z | = | 15467 2500 |
The coefficient of the unknown number is reduced to 1 :
| Z | = | 15467 2500 | ÷ | 21 40 |
| = | 15467 2500 | × | 40 21 |
| = | 15467 125 | × | 2 21 |
We obtained :
| Z | = | 30934 2625 |
Convert the result to decimal form :
| Z | = | 11.784381 |
