Work: Find the solution of equation x/(2-x) = 2.18 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 2 | − | x | ) | = | 109 50 |
| Multiply both sides of the equation by: | ( | 2 | − | x | ) |
| x | = | 109 50 | ( | 2 | − | x | ) |
| x | = | 109 50 | × | 2 | − | 109 50 | x |
| x | = | 109 25 | − | 109 50 | x |
Transposition :
| x | + | 109 50 | x | = | 109 25 |
Combine the items on the left of the equation:
159 50 | x | = | 109 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 109 25 | ÷ | 159 50 |
| = | 109 25 | × | 50 159 |
| = | 109 | × | 2 159 |
We obtained :
| x | = | 218 159 |
Convert the result to decimal form :
| x | = | 1.371069 |
