[ 1/1 Equation]
Work: Find the solution of equation (499-X)/X = -0.3011 .
Question type: Equation
Solution:Original question:
| ( | 499 | − | X | ) | ÷ | X | = | - | 3011 10000 |
| Multiply both sides of the equation by: | X |
| ( | 499 | − | X | ) | = | - | 3011 10000 | X |
| 499 | − | X | = | - | 3011 10000 | X |
Transposition :
| - | X | + | 3011 10000 | X | = | - | 499 |
Combine the items on the left of the equation:
| - | 6989 10000 | X | = | - | 499 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 499 | = | 6989 10000 | 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 :
6989 10000 | X | = | 499 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 499 | ÷ | 6989 10000 |
| = | 499 | × | 10000 6989 |
We obtained :
| X | = | 4990000 6989 |
Convert the result to decimal form :
| X | = | 713.97911 |
