    do you have an example? they are just like equations but with a slight hiccup in them

    when we multiply or divide them by a negative number; we need to reverse the symbol, and heres why 5 > 3 ; multiply both sides by -1 -5 > -3 is false; so we flip the symbol to account for it

    'wait what' is not a comprehensible response that i can really respond to.

    ok how would we solve for 'p' if this was an equation?

    add 3 to both sides?

    then do that with this :) p > -3 is the answer

    oh well what about this one? -2y<10 - this btw is a less than or equal to sign

    -2y </ 10 how would we normally solve something like this?

    that i do not know but i think it has something to do with division

    your are right about that :) divide both sides by -2

    -2y has a -2 stuck to it right? its is multiplied right on there..

    how do we undo multiplication?

    then to unstick it; we divide by -2 right :)

    then it would be -5

    yes .... but we have the hiccup here... we had to multiply or divide the y by a negative number... right?

    what do you mean by hiccup

    i mean that they dont tell you this little fact when you do equations because its redundant..... but whenever you have to multiply the variable by a negative number; ALWAYS flip your sign around..

    an = sign flip around looks like = so its a step they omit to tell you

    > flips around to be < < flips around to be > = flips around to be =

    so the answer would be y \[\ge\]-5

    Alternatively you can just swap the left and right sides by adding.. -2y < 10 +2y - 10 + 2y - 10 ============== -10 < 2y Then do the division normally.
