l 3m + 7 l < 28 How do I do this equation?

OpenStudy (saifoo.khan):

l 3m + 7 l < 28 l 3m + 7 l < 28 and l 3m + 7 l > - 28 solve both.

omg i just did tht problem no joke

OpenStudy (anonymous):

wow, what are the odds!

OpenStudy (turingtest):

why did you leave the absolute value bars? the system to solve is 3m + 7 < 28 and 3m + 7 > - 28

OpenStudy (ksaimouli):

3m + 7 l < 28 l 3m + 7 l < 28, if u do this both u canl 3m + 7 l > - 28

OpenStudy (karatechopper):

i have a trick though! i learned it today!

OpenStudy (anonymous):

What is it?

OpenStudy (karatechopper):

well the trick here is to put the -28 in of the 3m+7 with tthe same sign sign (your sign should not change it should still remain >) as one case and then the positive one as another case
