Work: Find the solution of equation 10%-x/10%-15% = 8300/122210 .
Question type: Equation
Solution:Original question:
10 100 | − | x | ÷ | 10 100 | − | 15 100 | = | 8300 | ÷ | 122210 |
| Left side of the equation = | - | 1 20 | − | 100 10 | x |
| - | 1 20 | − | 100 10 | x | = | 8300 | ÷ | 122210 |
| Right side of the equation = | 830 12221 |
| - | 1 20 | − | 100 10 | x | = | 830 12221 |
Transposition :
| - | 100 10 | x | = | 830 12221 | + | 1 20 |
Combine the items on the right of the equation:
| - | 100 10 | x | = | 28821 244420 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 28821 244420 | = | 100 10 | 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 10 | x | = | - | 28821 244420 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 28821 244420 | ÷ | 100 10 |
| = | - | 28821 244420 | × | 10 100 |
| = | - | 28821 24442 | × | 1 100 |
We obtained :
| x | = | - | 28821 2444200 |
Convert the result to decimal form :
| x | = | - 0.011792 |
