The answer would be 8.9.
Step-by-step explanation:

Since we want to get ' p ' on left hand side , remove the number ' - 6 '.
⇢
{ The opposite of -6 is +6 and whatever we do to one side , we must do to the another side. So, I added 6 on both sides }
⇢
{ On the left hand side , 6-6 = 0. That's how we removed the 6 so just 'p' is left. On the right hand side , 5+6 = 11 }
