Answer 1

x + 5 < -4

Explanation:

Example number -10

x+6<-8

-6 -6

————

x < 14
x can be -15, -16, etc

x+4>-6

-4 -4

————

x > -10

x can be -10, -9, etc

x-3>-10

+3 +3

————

x > -7

x can be -6, -5, etc

x +5<-4

-5 -5

—————

x < -9

x can be -10, -11, etc

Answer 2

1.)
x+6<-8
x<-8-6
x<-14

2.)
X+4>-6
X>-6-4
X>-10

3.)
X-3>-10
X>-10+3
