Work: Find the solution of equation 13000/x+5 = 8000/x .
Question type: Equation
Solution:Original question:
| 13000 | ÷ | x | + | 5 | = | 8000 | ÷ | x |
| Multiply both sides of the equation by: | x |
| 13000 | + | 5 | x | = | 8000 | ÷ | 1 | × | 1 |
Transposition :
| 5 | x | = | 8000 | ÷ | 1 | × | 1 | − | 13000 |
Calculate the items on the right of the equation:
| 5 | x | = | 8000 | − | 13000 |
Combine the items on the right of the equation:
| 5 | x | = | - | 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 5000 | ÷ | 5 |
| = | - | 5000 | × | 1 5 |
| = | - | 1000 | × | 1 |
We obtained :
| x | = | - | 1000 |
