Question

17=p-3-3p

Answer 1

Get the numbers on one side and variables on the other
So add 3 to each side
20=p-3p
Combine the p's
20=2p
divide each side by 2
10=p

Answer 2

Thanks!!! :)

Answer 3

@nathanB you made a mistake
20=p-3p
Combine the p's
20=2p

p-3p = -2p
-2p=20

So the answer is -10, not 10

Answer 4

I'm sorry. I forgot to keep the negative.
@thomaster Thanks for correcting me.
