Use the 'Options' tab and note two tips for simplifications: use 'a few steps' and use 'real numbers'.  This approach provides a simple solution and a decimal answer, which is what you are apparently inquiring about. 

An integer answer is exact, a decimal answer is an approximation.  As solution steps are increase then the additional steps are either helpful or confusing, so always check out the 'Options' tab when a solution is either confusing or too terse. 

Finally, clicking on a particular step allows you to review the logic which is employed.
