Sometimes there is no solution. Sometimes there is one yet it is impossible to have. For example in math we can't find the square root of -25 yet we can find a possible solution by making i into the equation now we have a solution yet impossible to find the answer to the solution. 5i we know it yet can't find it. What I'm trying to say is sometimes there is a solution yet the solution isn't always going to give the answer or the results.
