The simplified expression is #13#p. Here's why:

Explanation:

#6p - (-7)p#

First, according to PEMDAS, we need to start with our parentheses. Let's start with the #p# at the end of #(-7)# because it only distributes itself to #(-7)#.

You should now have:

#6p - (-7p)#

Now, ignore #6p# for now and distribute the negative sign to #(-7p)#:

#- (-7p)# becomes #(7p)# because two negatives create a positive. Throw #6p# back in there once you've this. You should now have:

#6p + 7p#

Add.

The simplified expression is: #13p#.
