Work: Find the solution of equation 05-0.1-(1+x)/x*0.1*0.3 = 0 .
Question type: Equation
Solution:Original question:
| 5 | − | 1 10 | − | ( | 1 | + | x | ) | ÷ | x | × | 1 10 | × | 3 10 | = | 0 |
| Multiply both sides of the equation by: | x |
| 5 | x | − | 1 10 | x | − | ( | 1 | + | x | ) | × | 1 10 | × | 3 10 | = | 0 |
| 5 | x | − | 1 10 | x | − | 1 | × | 1 10 | × | 3 10 | − | x | × | 1 10 | × | 3 10 | = | 0 |
| 5 | x | − | 1 10 | x | − | 3 100 | − | x | × | 3 100 | = | 0 |
487 100 | x | − | 3 100 | = | 0 |
Transposition :
487 100 | x | = | 0 | + | 3 100 |
Combine the items on the right of the equation:
487 100 | x | = | 3 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3 100 | ÷ | 487 100 |
| = | 3 100 | × | 100 487 |
| = | 3 | × | 1 487 |
We obtained :
| x | = | 3 487 |
Convert the result to decimal form :
| x | = | 0.00616 |
