|4x-9|+20>35

OpenStudy (mathlegend):

My first answer was x>6

OpenStudy (mathlegend):

and then I got x<-11.5

OpenStudy (jiteshmeghwal9):

|4x-9|=-(4x-9) =-4x+9 & |4x-9|=4x-9

OpenStudy (anonymous):

|4x-9|>35-20 |4x-9|>15 solve the following two equations 4x-9>15 4x-9<-15

OpenStudy (jiteshmeghwal9):

so one time -4x+9+20>35 -4x+29>35 -4x>35-29 -4x>6 x>6/-4 x>3/-2

OpenStudy (jiteshmeghwal9):

& one time 4x-9+20>35 4x+11>35 4x>35-11 4x>24 x>24/4 x>6

OpenStudy (anonymous):

\[|4x-9|+20>35 \rightarrow |4x-9|>35-20\]

OpenStudy (anonymous):

|4x-9|>35-20 |4x-9|>15 solve the following two equations 4x-9>15 4x-9<-15 4x>15+9 x>24/4 x>6 now 4x-9<-19 4x<-15+9 4x<-6 x<-6/4 x<-3/2

OpenStudy (anonymous):

where did -19 come from?

hartnn (hartnn):

just a typo i guess,next steps are correct....

OpenStudy (anonymous):

k, I just woke up and I thought I might be seeing things incorrectly

OpenStudy (anonymous):

so the next value of x should be solved in the form of: \[-|4x-9|>15\] which gives us \[-4x+9>15\]

OpenStudy (anonymous):

@panlac01 sorry -19 is typo mistake .
