☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation 2/x = {2/（2-x）}+5 .
Question type: Equation
Solution:Original question:
| 2 | ÷ | x | = | ( | 2 | ÷ | ( | 2 | − | x | ) | ) | + | 5 |
| Multiply both sides of the equation by: | x |
| 2 | = | ( | 2 | ÷ | ( | 2 | − | x | ) | ) | x | + | 5 | x |
| 2 | = | 2 | ÷ | ( | 2 | − | x | ) | × | x | + | 5 | x |
| Multiply both sides of the equation by: | ( | 2 | − | x | ) |
| 2 | ( | 2 | − | x | ) | = | 2 | x | + | 5 | x | ( | 2 | − | x | ) |
| 2 | × | 2 | − | 2 | x | = | 2 | x | + | 5 | x | ( | 2 | − | x | ) |
| 2 | × | 2 | − | 2 | x | = | 2 | x | + | 5 | x | × | 2 | − | 5 | x | x |
| 4 | − | 2 | x | = | 2 | x | + | 10 | x | − | 5 | x | x |
| 4 | − | 2 | x | = | 12 | x | − | 5 | x | x |
The solution of the equation:
x1≈0.322967 , keep 6 decimal places
x2≈2.477033 , keep 6 decimal places
There are 2 solution(s).
