Work: Find the solution of equation 2.56 = （57-x/57）*100 .
Question type: Equation
Solution:Original question:
64 25 | = | ( | 57 | − | x | ÷ | 57 | ) | × | 100 |
| Right side of the equation = | 57 | × | 100 | − | x | ÷ | 57 | × | 100 |
| = | 5700 | − | x | × | 100 57 |
64 25 | = | 5700 | − | 100 57 | x |
Transposition :
100 57 | x | = | 5700 | − | 64 25 |
Combine the items on the right of the equation:
100 57 | x | = | 142436 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 142436 25 | ÷ | 100 57 |
| = | 142436 25 | × | 57 100 |
| = | 35609 25 | × | 57 25 |
We obtained :
| x | = | 2029713 625 |
Convert the result to decimal form :
| x | = | 3247.5408 |
