Answer:

x<30

Explanation:

-2x-4> -64

add 4 to both sides

-2x-4+4> -64+4

simplify the arithmetic

-2x> -64+4

-2x>-60

divide both side by -2

When dividing or multiplying by a negative number, always flip the inequality sign

-2x/-2 <-60/-2

Cancel out the negatives:

2x/2<-60/-2

Simplify the fraction:

x<-60/-2

Cancel out the negatives:

x<60/2

Find the greatest common factor of the numerator and denominator:

x<30 . 2 / 1 . 2

Factor out and cancel the greatest common factor:

x<30
