Work: Find the solution of equation 20.46 = -3.9423x+43.147 .
Question type: Equation
Solution:Original question:
1023 50 | = | - | 39423 10000 | x | + | 43147 1000 |
Transposition :
39423 10000 | x | = | 43147 1000 | − | 1023 50 |
Combine the items on the right of the equation:
39423 10000 | x | = | 22687 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 22687 1000 | ÷ | 39423 10000 |
| = | 22687 1000 | × | 10000 39423 |
| = | 22687 | × | 10 39423 |
We obtained :
| x | = | 226870 39423 |
Convert the result to decimal form :
| x | = | 5.754762 |
