Answer:
the answer is p = 15
Explanation:
first you set the equation to 2p + 9 = 3p - 6
then solve out the equation by adding 6 to both sides
the equation will now look like this, 2p + 15 = 3p
now you subtract 2p from both sides
the equation now looks like 15 = p
I always flip my equations so I can read it better,
p = 15
