Answer 7

So I say you again :
-x-4x=-5x
and we have :
-5x<0
So divided on -5 and have :
x<0
Got it ?:)

Answer 8

-x - 4x < 0

you can simplify -x - 4 x to -5x

-5x < 0

notice dividing by a negative number changes the relation operator

However, we can add +5x to both sides to get
-5x + 5x < 5x
0 < 5x

now we can divide both sides by 5 to get
0/5 < 5x/5
which simplifies to
0 < x

Answer 9

0<x
