HanAkoSolo (jamierox4ev3r):

do you want to know how I came to that answer?

OpenStudy (anonymous):

Yes plz

HanAkoSolo (jamierox4ev3r):

all right,give me a sec.

HanAkoSolo (jamierox4ev3r):

first, you add 5 to both sides

HanAkoSolo (jamierox4ev3r):

Then, you have 4m>-9 or 4m<3

HanAkoSolo (jamierox4ev3r):

then, you divide both sides by four.

HanAkoSolo (jamierox4ev3r):

you get m>-9 or m<3

HanAkoSolo (jamierox4ev3r):

that is your final answer, and no it is not no solution sorry about that

OpenStudy (anonymous):

But if you add 5 to both sides shouldn't it be 4m > -4 and 4m < 8?

HanAkoSolo (jamierox4ev3r):

congrats, you figured out my error... nice. Then, your final answer, in that case, is m>-1 or m<2
