is this solution insoluble

Answer provided by our tutors

It is important to understand that if integer arithmetics is chosen, then all decimal numbers will be converted to integer fractions as part of the solution process. This may produce a solution that is long and somewhat confusing. 

Therefor, click on the 'Options' and select integer or real arithmetics to be used during the solution process (e.g., x=1/2 vs. x=0.5). Integer is selected by default, and in the case of your equation I switched integer to real (decimal) numbers and clicked on 'Apply':

That is how I got the following solutions:

So, the equation is not insoluble since it has 2 real solutions.
