Work: Find the solution of equation 3387*0.562*(794+x-18) = 875 .
Question type: Equation
Solution:Original question:
| 3387 | × | 281 500 | ( | 794 | + | x | − | 18 | ) | = | 875 |
| Left side of the equation = | 951747 500 | ( | 794 | + | x | − | 18 | ) |
951747 500 | ( | 794 | + | x | − | 18 | ) | = | 875 |
| Left side of the equation = | 951747 500 | × | 794 | + | 951747 500 | x | − | 951747 500 | × | 18 |
| = | 377843559 250 | + | 951747 500 | x | − | 8565723 250 |
| = | 184638918 125 | + | 951747 500 | x |
184638918 125 | + | 951747 500 | x | = | 875 |
Transposition :
951747 500 | x | = | 875 | − | 184638918 125 |
Combine the items on the right of the equation:
951747 500 | x | = | - | 184529543 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 184529543 125 | ÷ | 951747 500 |
| = | - | 184529543 125 | × | 500 951747 |
| = | - | 184529543 | × | 4 951747 |
We obtained :
| x | = | - | 738118172 951747 |
Convert the result to decimal form :
| x | = | - 775.540319 |
