Work: Find the solution of equation 100x/（100－2x） = 3.06 .
Question type: Equation
Solution:Original question:
| 100 | x | ÷ | ( | 100 | − | 2 | x | ) | = | 153 50 |
| Multiply both sides of the equation by: | ( | 100 | − | 2 | x | ) |
| 100 | x | = | 153 50 | ( | 100 | − | 2 | x | ) |
| 100 | x | = | 153 50 | × | 100 | − | 153 50 | × | 2 | x |
| 100 | x | = | 306 | − | 153 25 | x |
Transposition :
| 100 | x | + | 153 25 | x | = | 306 |
Combine the items on the left of the equation:
2653 25 | x | = | 306 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 306 | ÷ | 2653 25 |
| = | 306 | × | 25 2653 |
We obtained :
| x | = | 7650 2653 |
Convert the result to decimal form :
| x | = | 2.883528 |
