Work: Find the solution of equation X/(X-9.456) = 4.2 .
Question type: Equation
Solution:Original question:
| X | ÷ | ( | X | − | 1182 125 | ) | = | 21 5 |
| Multiply both sides of the equation by: | ( | X | − | 1182 125 | ) |
| X | = | 21 5 | ( | X | − | 1182 125 | ) |
| X | = | 21 5 | X | − | 21 5 | × | 1182 125 |
| X | = | 21 5 | X | − | 24822 625 |
Transposition :
| X | − | 21 5 | X | = | - | 24822 625 |
Combine the items on the left of the equation:
| - | 16 5 | X | = | - | 24822 625 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
24822 625 | = | 16 5 | 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 :
16 5 | X | = | 24822 625 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 24822 625 | ÷ | 16 5 |
| = | 24822 625 | × | 5 16 |
| = | 12411 125 | × | 1 8 |
We obtained :
| X | = | 12411 1000 |
Convert the result to decimal form :
| X | = | 12.411 |
