Question

...

Answer 1

when you have an absolute value you can write it as such and solve


-9<x+5<9

Answer 2

IxI<4 = x<4

Answer 3

wrong it's x+5<9 or x+5>-9

Answer 4

No it's not.

Answer 5

You always solve on the variable side.

Answer 6

does it make any sense to solve

x+5<9 and x+5<-9....if you already know that x+5<9

Answer 7

and that isn't correct compassionate you're completely disregarding the absolute value

Answer 8

Please explain how you solved it. I seem to be misconstruing the information

Answer 9

-9<x+5<9

if you subtract 5 to both sides you get

-14<x<4

which is the same as

x>-14 and x<4

Answer 10

Case1
x<-5
then, Ix+5I=-(x+5)
so,
-x-5<9
-x<14
x>-14
but x<-5

therefore , x belongs to (-14,-5)..........................1

Case2,
x>-5
then, Ix+5I=x+5
x+5<9
x<4
but x>-5
so, x belongs to (-5,4)...............2

union of 1 and 2 is the soution.
x belongs to (-14,-5)U(-5,4)

Answer 11

I said x<4...
