Answer:

x < -3/4 OR x>16/5

Explanation:

5x – 4 > 12 OR 12x+5 < -4

Solve the parts separately and then put back together

5x – 4 > 12

Add 4 to each side

5x-4+4>12+4

5x >16

Divide each side by 5

5x/5>16/5

x > 16/5

12x+5 < -4

Subtract 5 from each side

12x+5-5<-4-5

12x<-9

Divide each side by 12

12x<-9/12

x <-3/4

Put back together

x < -3/4 OR x>16/5
