Work: Find the solution of equation 8427.6 = 1813.7*x+405.49 .
Question type: Equation
Solution:Original question:
42138 5 | = | 18137 10 | x | + | 40549 100 |
Transposition :
| - | 18137 10 | x | = | 40549 100 | − | 42138 5 |
Combine the items on the right of the equation:
| - | 18137 10 | x | = | - | 802211 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
802211 100 | = | 18137 10 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
18137 10 | x | = | 802211 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 802211 100 | ÷ | 18137 10 |
| = | 802211 100 | × | 10 18137 |
| = | 802211 10 | × | 1 18137 |
We obtained :
| x | = | 802211 181370 |
Convert the result to decimal form :
| x | = | 4.423063 |
