Work: Find the solution of equation 2*x/（1+x） = 0.28571 .
Question type: Equation
Solution:Original question:
| 2 | x | ÷ | ( | 1 | + | x | ) | = | 28571 100000 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| 2 | x | = | 28571 100000 | ( | 1 | + | x | ) |
| 2 | x | = | 28571 100000 | × | 1 | + | 28571 100000 | x |
| 2 | x | = | 28571 100000 | + | 28571 100000 | x |
Transposition :
| 2 | x | − | 28571 100000 | x | = | 28571 100000 |
Combine the items on the left of the equation:
171429 100000 | x | = | 28571 100000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 28571 100000 | ÷ | 171429 100000 |
| = | 28571 100000 | × | 100000 171429 |
| = | 28571 | × | 1 171429 |
We obtained :
| x | = | 28571 171429 |
Convert the result to decimal form :
| x | = | 0.166664 |
