@Joel_the_boss

JoelTheBoss (joel_the_boss):

solve for X?

OpenStudy (rainbow_dashie):

yas

OpenStudy (anonymous):

-4x - 15 < 17 17 + 15 = ? ? / (-4) = x

OpenStudy (rainbow_dashie):

?

OpenStudy (rainbow_dashie):

halp

OpenStudy (anonymous):

what is 17 + 15 ? can you answer that?

OpenStudy (rainbow_dashie):

32

JoelTheBoss (joel_the_boss):

Add 15 to both sides \[−4x<17+15 \]

JoelTheBoss (joel_the_boss):

Simplify 17+15 to 32\[−4x<32 \]

OpenStudy (rainbow_dashie):

\[-4<32\]

OpenStudy (anonymous):

okay, so, not do 32 / -4

OpenStudy (imtiaz7):

-4x-15<17 -4x<17+15 -4x<32 x<32/-4 x<-8

JoelTheBoss (joel_the_boss):

Multiply both sides by −1

OpenStudy (anonymous):

*now @Imtiaz7 , thank you.

JoelTheBoss (joel_the_boss):

\[4x>-32 \]

JoelTheBoss (joel_the_boss):

Divide both sides by 4

OpenStudy (rainbow_dashie):

\[4\div32=8\]

JoelTheBoss (joel_the_boss):

\[x>-\frac{ 32 }{ 4}\]

JoelTheBoss (joel_the_boss):

you got it right :)

OpenStudy (rainbow_dashie):

so \[x<-8\]

OpenStudy (rainbow_dashie):

Thank you

OpenStudy (anonymous):

kk :)

JoelTheBoss (joel_the_boss):

\[x>-8\] is what I got but then you flip the sign if its a negative which makes you correct
