Question

Solve for x: 3 − (2x − 5) < −4(x + 2)

Answer 1

PEMDAS...

factor out to remove the parenthesis,
combine like terms
and isolate X by itself

you will change the direction of the sign, only when you divide by NEGATIVE number

Answer 2

2x-5 is -3x right ?

Answer 3

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

Answer 4

Oh , thank you .

Answer 5

No you can not combine 2x and -5 to get -3x

remember rule is you combine LIKE terms only - those are not LIKE

Answer 6

So its not x<-8 ?
