    Cool Inequality check. <no rush>

    alright. i'm new at this. i think i know what i'm doing., but. i just need to make sure everything is correct.

    3x + 3 < 8x - 7
    = 3x-8x<-7-3
    =-5x<-10
    =x<2

    This right?

    alright., i'm new at this as well . but, heres my look on things

    You did everything correctly til' you got to your final answer.
    whenever you divide by a negative your < changes to > .
    thats the only problem i see. everything else looks fine to me.

    Hope this helps :d
