Work: Find the solution of equation 945938*0.45-x = 0.44*(945938-x) .
Question type: Equation
Solution:Original question:
| 945938 | × | 9 20 | − | x | = | 11 25 | ( | 945938 | − | x | ) |
| Left side of the equation = | 4256721 10 | − | x |
4256721 10 | − | x | = | 11 25 | ( | 945938 | − | x | ) |
| Right side of the equation = | 11 25 | × | 945938 | − | 11 25 | x |
| = | 10405318 25 | − | 11 25 | x |
4256721 10 | − | x | = | 10405318 25 | − | 11 25 | x |
Transposition :
| - | x | + | 11 25 | x | = | 10405318 25 | − | 4256721 10 |
Combine the items on the left of the equation:
| - | 14 25 | x | = | 10405318 25 | − | 4256721 10 |
Combine the items on the right of the equation:
| - | 14 25 | x | = | - | 472969 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
472969 50 | = | 14 25 | 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 :
14 25 | x | = | 472969 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 472969 50 | ÷ | 14 25 |
| = | 472969 50 | × | 25 14 |
| = | 67567 2 | × | 1 2 |
We obtained :
| x | = | 67567 4 |
Convert the result to decimal form :
| x | = | 16891.75 |
