Work: Find the solution of equation （618100-63.1x）*0.73+x = 423931 .
Question type: Equation
Solution:Original question:
| ( | 618100 | − | 631 10 | x | ) | × | 73 100 | + | x | = | 423931 |
| Left side of the equation = | 618100 | × | 73 100 | − | 631 10 | x | × | 73 100 | + | x |
| = | 451213 | − | 46063 1000 | x | + | x |
| = | 451213 | − | 45063 1000 | x |
| 451213 | − | 45063 1000 | x | = | 423931 |
Transposition :
| - | 45063 1000 | x | = | 423931 | − | 451213 |
Combine the items on the right of the equation:
| - | 45063 1000 | x | = | - | 27282 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 27282 | = | 45063 1000 | 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 :
45063 1000 | x | = | 27282 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 27282 | ÷ | 45063 1000 |
| = | 27282 | × | 1000 45063 |
| = | 9094 | × | 1000 15021 |
We obtained :
| x | = | 9094000 15021 |
Convert the result to decimal form :
| x | = | 605.41908 |
