it's fine I 'm finish
OpenStudy (anonymous):
but it says 3over 4( 3x - 1over 2)minus 2over 3 < 1 over 3
OpenStudy (anonymous):
you can understand that
OpenStudy (anonymous):
\[\frac{3}{4}(3x-\frac{1}{2})-\frac{2}{3}<\frac{1}{3}\]
OpenStudy (anonymous):
yes u got it

clear the annoying fractions by multiplying both sides by 12
OpenStudy (anonymous):
how did you get it to show like that. I tried
OpenStudy (anonymous):
\[9(3x-\frac{1}{2})-8<4\]
OpenStudy (anonymous):
oh wow
OpenStudy (anonymous):
add 8 to both sides
\[9(3x-\frac{1}{2})<12\]

OpenStudy (anonymous):
divide both sides by 9
\[3x-\frac{1}{2}<\frac{4}{3}\]
OpenStudy (anonymous):
if u add 8 how did u still have 9(3x
OpenStudy (anonymous):
this is hard
OpenStudy (anonymous):
add one half
\[3x<\frac{11}{6}\]
OpenStudy (anonymous):
divide by 3 get
\[x<\frac{11}{12}\]

i added 8 which was out side of the parentheses
OpenStudy (anonymous):
okay so do whats on the outside first
OpenStudy (anonymous):
i was always told to do inside first PEMDAS
OpenStudy (anonymous):
you could have multiplied out first and then collected terms. i found this way easier
OpenStudy (anonymous):
pemdas is for evaluating

okay this is how I keep getting stuck then
OpenStudy (anonymous):
the only reason this is so annoying is because of the fractions. if it was whole numbers it would be easier
OpenStudy (anonymous):
if you want we can redo this whole thing multiplying out first. but then it will we really annoying
OpenStudy (anonymous):
yeah and i have a test coming up with these on it
OpenStudy (anonymous):

Thank you so much I am trying to do this home work and these problems just have me stuck
OpenStudy (anonymous):
don't forget to clear fractions which will make life easier
OpenStudy (anonymous):
so how did you know to use 12 to clear it
OpenStudy (anonymous):
Is it because of the 3 and the 4 as the donominator
