solve and graph the following inequality 14z + 9 - 9z < 6z + 21

OpenStudy (anonymous):

combine like terms on the left, subtract the result off of both sides, subtract the 21 off both sides. you should be at -#<z.... follow me?..

OpenStudy (anonymous):

yes, i think i'm having the problem lining them up

OpenStudy (anonymous):

14z and 9z

OpenStudy (anonymous):

yes, so 14z-9z = ??z

OpenStudy (anonymous):

5z

OpenStudy (anonymous):

ok now your left with 5z + 9 < 6z +21? right

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

combine like terms again right

OpenStudy (anonymous):

subtract the 5z off of both sides to get rid of it on the left.

OpenStudy (anonymous):

careful combine like terms is for on the same side of the equation..

OpenStudy (anonymous):

ok that's where i've been making the mistake i have to remember that

OpenStudy (anonymous):

then subtract 21 from both sides to get rid of it on the right... leaving what?
