Problem
For which of the following values of does the equation have no solution for ?
Solution
The domain over which we solve the equation is .
We can now cross-multiply to get rid of the fractions, we get .
Simplifying that, we get . Clearly for we get the equation which is never true. The answer is
For other , one can solve for : , hence . We can easily verify that for none of the other four possible values of is this equal to or , hence there is a solution for in each of the other cases.
