Answer:
To get this answer, we need to use the equation for it, which is 7x + 12 = 33. Then, we will use SADMEP (reverse order of operations) to solve this equation. First, we will subtract 12 from both sides to get the variable by itself. This leaves us with 7x = 21. We will then divide both sides by 7 to get x alone, leaving us with the answer x = 3. So, there were three friends.
