Work: Find the solution of equation 2405*56.2%*1.25*0.8*794/（794+x-18） = 932 .
Question type: Equation
Solution:Original question:
| 2405 | × | 281 500 | × | 5 4 | × | 4 5 | × | 794 | ÷ | ( | 794 | + | x | − | 18 | ) | = | 932 |
| Multiply both sides of the equation by: | ( | 794 | + | x | − | 18 | ) |
| 2405 | × | 281 500 | × | 5 4 | × | 4 5 | × | 794 | = | 932 | ( | 794 | + | x | − | 18 | ) |
| 2405 | × | 281 500 | × | 5 4 | × | 4 5 | × | 794 | = | 932 | × | 794 | + | 932 | x | − | 932 | × | 18 |
53658917 50 | = | 740008 | + | 932 | x | − | 16776 |
53658917 50 | = | 723232 | + | 932 | x |
Transposition :
| - | 932 | x | = | 723232 | − | 53658917 50 |
Combine the items on the right of the equation:
| - | 932 | x | = | - | 17497317 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
17497317 50 | = | 932 | 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 :
| 932 | x | = | 17497317 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 17497317 50 | ÷ | 932 |
| = | 17497317 50 | × | 1 932 |
We obtained :
| x | = | 17497317 46600 |
Convert the result to decimal form :
| x | = | 375.478906 |
