Answer:
To find the answer to this equation you need to get p by itself
To do this you need to do the opposite of what is happening to your variable
p is being divided by 4, so to get p by itself you need to take 4 and multiply it to both sides (what you do to one side you need to do to the other)
5*4=20
p/4*4=p
So p=20
p=20
Hope this helps ;)
