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
