# Pulling answer from previous output

This will probably be a very simple answer. I am trying to find a way to pull the last output from a line and define it as a separate variable so it can be used in a later function. Specifically in the code below:


In[5]:= NSolve[90 - 3*p == (4*p) - 20, p]

Out[5]= {{p -> 15.7143}}
