Work: Find the solution of equation 2446*0.562*794/(794+x-18) = 669 .
Question type: Equation
Solution:Original question:
| 2446 | × | 281 500 | × | 794 | ÷ | ( | 794 | + | x | − | 18 | ) | = | 669 |
| Multiply both sides of the equation by: | ( | 794 | + | x | − | 18 | ) |
| 2446 | × | 281 500 | × | 794 | = | 669 | ( | 794 | + | x | − | 18 | ) |
| 2446 | × | 281 500 | × | 794 | = | 669 | × | 794 | + | 669 | x | − | 669 | × | 18 |
136434211 125 | = | 531186 | + | 669 | x | − | 12042 |
136434211 125 | = | 519144 | + | 669 | x |
Transposition :
| - | 669 | x | = | 519144 | − | 136434211 125 |
Combine the items on the right of the equation:
| - | 669 | x | = | - | 71541211 125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
71541211 125 | = | 669 | 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 :
| 669 | x | = | 71541211 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 71541211 125 | ÷ | 669 |
| = | 71541211 125 | × | 1 669 |
We obtained :
| x | = | 71541211 83625 |
Convert the result to decimal form :
| x | = | 855.500281 |
