  • algebra check please -

    -8 - 5y = 12 - 9y

    -5y + 9y = 12 + 8

    4y = 20

    y = 5

    thanks and to check
    -8 -5(5) = 12 -9 (5)
    -8-25 = 12 - 45
    -33 = -33 true
    thanks
    got time for 1 more -- please :)

    8 - 3 (p-4) = 2p
    i got:

    8 - 3p - 12 = 2p
    now im stuck

  • algebra check please -

    You're welcome.

    8 - 3 (p-4) = 2p

    8 - 3p + 12 = 2p

    20 = 2p + 3p

    20 = 5p

    4 = p

    You seem to be forgetting that multiplying two negative numbers produces a positive number. Watch your signs!

    wait i think i got it:
    8 - 3p -12 = 2p
    12 + 8 = 20
    20 - 3p = 2p
    +3p = +3p
    20 = 5p
    -------------
    5 5

    4 = p is that right

    Yay! You've got it!
