    3-2p+4

    = 7-6p

    you have an error in the second step:

    3-2p+4 equals 7-2p and not 7-6p

    3-2p+4 Mr F says: This line is correct.

    = 7-6p Mr F says: This line is INcorrect.

    3 - 2p + 4 = 3 + 4 - 2p = 7 - 2p. And that's it. Done.

    If your goal is just to simplify it, then I got 7 - 2p (you reverted back to 6p).
