Work: Find the solution of equation 100-x/x = 0.08 .
Question type: Equation
Solution:Original question:
| 100 | − | x | ÷ | x | = | 2 25 |
| Multiply both sides of the equation by: | x |
| 100 | x | − | x | = | 2 25 | x |
Transposition :
| 100 | x | − | x | − | 2 25 | x | = | 0 |
Combine the items on the left of the equation:
2473 25 | x | = | 0 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 0 | ÷ | 2473 25 |
| = | 0 | × | 25 2473 |
We obtained :
| x | = | 0 |
| x | = | 0 |
