Question type: Equation
Solution:Original question:
| - | 38663 500 | x | × | 6 | + | 1181 5 | x | × | 5 | − | 5667 20 | x | × | 4 | + | 4233 25 | x | × | 3 | = | 3991 5000 |
| Left side of the equation = | - | 115989 250 | x | + | 1181 | x | − | 5667 5 | x | + | 12699 25 | x | − | 26209 250 | x | + | 82477 10000 | x |
| = | - | 49843 10000 | x | + | 131 10000 |
| - | 49843 10000 | x | + | 131 10000 | = | 3991 5000 |
Transposition :
| - | 49843 10000 | x | = | 3991 5000 | − | 131 10000 |
Combine the items on the right of the equation:
| - | 49843 10000 | x | = | 7851 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 7851 10000 | = | 49843 10000 | 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 :
49843 10000 | x | = | - | 7851 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 7851 10000 | ÷ | 49843 10000 |
| = | - | 7851 10000 | × | 10000 49843 |
| = | - | 7851 | × | 1 49843 |
We obtained :
| x | = | - | 7851 49843 |
Convert the result to decimal form :
| x | = | - 0.157515 |
