Work: Find the solution of equation 2 = 1/(1/(1-x)) .
Question type: Equation
Solution:Original question: Multiply both sides of the equation by: | ( | 1 | ÷ | ( | 1 | − | x | ) | ) |
Remove a bracket on the left of the equation::
The equation is reduced to :
Multiply both sides of the equation by: | ( | 1 | − | x | ) |
Remove a bracket on the right of the equation::
The equation is reduced to :
Transposition :
i.e.
Combine the items on the right of the equation:
However,when simplifying the equation, multiply both sides by ( | 1 | ÷ | ( | 1 | − | x | ) | ) | , and when
, its value is 0. Therefore, the value of this unknown number is not the solution of the equation, and the input to the equation is incorrect.
