Work: Find the solution of equation （33.77-x）/33.77 = -0.06 .
Question type: Equation
Solution:Original question:
| ( | 3377 100 | − | x | ) | ÷ | 3377 100 | = | - | 3 50 |
| Left side of the equation = | 3377 100 | × | 100 3377 | − | x | × | 100 3377 |
| = | 1 | − | x | × | 100 3377 |
| 1 | − | 100 3377 | x | = | - | 3 50 |
Transposition :
| - | 100 3377 | x | = | - | 3 50 | − | 1 |
Combine the items on the right of the equation:
| - | 100 3377 | x | = | - | 53 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
53 50 | = | 100 3377 | 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 :
100 3377 | x | = | 53 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 53 50 | ÷ | 100 3377 |
| = | 53 50 | × | 3377 100 |
We obtained :
| x | = | 178981 5000 |
Convert the result to decimal form :
| x | = | 35.7962 |
