-4<|6x-1|+4

-4-4 < |6x-1|

-8 < |6x-1|

|6x - 1| > -8

Since the absolute value of any number is NEVER negative, this means that |6x-1| is ALWAYS larger than any negative number you can think of.

Therefore, |6x - 1| > -8 is ALWAYS true for ANY x value

So -4<|6x-1|+4 has infinitely many solutions and that means you can plug in any value for x and it will be true.

So again, there are infinitely many solutions and you can say the solution set is the set of real numbers.

-4<|6x-1|+4
solve for 2 cases:
case 1
-4<6x-1+4
-7<6x
x>-7/6
..
case 2
-4<-6x+1+4
-6x>-9
6x<9
x<9/6=3/2
solution: (-7/6,3/2)
