help help! medal if correct.... Solve for x: 3 − (2x − 5) < −4(x + 2)

OpenStudy (anonymous):

x < −8 x > −8 x < −3 x > −3

OpenStudy (anonymous):

can anyone help?

OpenStudy (misty1212):

HI!

OpenStudy (anonymous):

i don't understand it

OpenStudy (misty1212):

\[3-(2x-5)<-4(x+2)\] we got to get rid of the parentheses first

OpenStudy (anonymous):

ok

OpenStudy (misty1212):

distibutive property \[3-2x+5<-4x-8\] or \[-2x+8<-4x-8\]

OpenStudy (misty1212):

add \(4x\) to both sides, tell me what you get

OpenStudy (anonymous):

you get 6x

OpenStudy (misty1212):

no be careful with your signs

OpenStudy (misty1212):

\[-2x+4x=?\]

OpenStudy (anonymous):

ooo 2x?

OpenStudy (anonymous):

ohh*

OpenStudy (anonymous):

so 16

OpenStudy (misty1212):

oops \[2x+8<-8\] add \(8\) to both sides

OpenStudy (anonymous):

so 0?

OpenStudy (anonymous):

2x<0?

OpenStudy (misty1212):

yeah \[2x<0\\ x<0\] is the final answer

OpenStudy (misty1212):

ok i see that is not a choice lets go back

OpenStudy (anonymous):

so what would be the answer out of these... x < −8 x > −8 x < −3 x > −3

OpenStudy (misty1212):

i made a mistake

OpenStudy (anonymous):

ok were do we start

OpenStudy (misty1212):

the answer is \(x<-8\)

OpenStudy (misty1212):

\[3 − (2x − 5) < −4(x + 2)\] \[3-2x+5<-4x-8\\ -2x+8<-8x-8\\ 2x+8<-8\\ 2x<-16\\ x<-8\]

OpenStudy (anonymous):
