Answer:
SOLUTION SET={x/x>-1} and SOLUTION SET={x/x<-1}
Step-by-step explanation:
1)4x-39>-43
evaluating the inequality
adding 39 on both sides
4x-39+39>-43+39
4x>-4
dividing 4 on both sides
4x/4>-4/4
x>-1
SOLUTION SET={x/x>-1}
2)8x+31<23
evaluating the inequality
subtracting 31 on both sides
8x+31-31<23-31
8x<-8
dividing 8 on both sides
8x/8<-8/8
x<-1
SOLUTION SET={x/x<-1}
i hope this will help you :)
