Given:


3x-1>5\text{ or }(x)/(2)-4<-5

To find the solutions for this compound inequality, we will first need to solve for x.


3x-1>5
3x>5+1
3x>6
x>2

Since x > 2, this would give us an interval notation of ( 2, ∞ )


(x)/(2)-4<-5
(x)/(2)<-5+4
(x)/(2)<-1
x<-1(2)
x<-2

Now, since x < -2, this will give us an interval notation of ( -∞, -2 )

Since we see the word OR in our compound inequality, this would mean that the solution for this is ( -∞, -2 ) ∪ ( 2, ∞ )
