Answer:
I believe the answer to your question is p = 33
Explanation:
Question: p÷3 - 7.2 = 3.8
Step 1: Add 7.2 to both sides of the equation
p÷3 - 7.2 = 3.8
+7.2 +7.2
p÷3 = 11
Adding 7.2 to both sides cancels out 7.2 on the left and whatever you do unto one side of an equation, you must do to the other (it's just a rule in math)
Step 2: Multiply by 3 on both sides
p÷3 = 11
x 3 x 3
p = 33
Same as last time; multiplying by 3 cancels out 3 on the left and whatever you do unto one side, you must do to the other
