Question type: Equation
Solution:Original question:
3933 10 | = | - | 17516 | x | × | 5 | + | 45861 | x | × | 4 | − | 28988 | x | × | 3 | + | 36431 10 | x | × | 2 |
| Right side of the equation = | - | 87580 | x | + | 183444 | x | − | 86964 | x | + | 36431 5 | x | − | 809 4 | x | + | 84451 100 |
| = | 319679 20 | x | + | 84451 100 |
3933 10 | = | 319679 20 | x | + | 84451 100 |
Transposition :
| - | 319679 20 | x | = | 84451 100 | − | 3933 10 |
Combine the items on the right of the equation:
| - | 319679 20 | x | = | 45121 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 45121 100 | = | 319679 20 | 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 :
319679 20 | x | = | - | 45121 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 45121 100 | ÷ | 319679 20 |
| = | - | 45121 100 | × | 20 319679 |
| = | - | 45121 5 | × | 1 319679 |
We obtained :
| x | = | - | 45121 1598395 |
Convert the result to decimal form :
| x | = | - 0.028229 |
