Question

What is the solution set of |4x – 3| – 1 > 12?

Answer 1

|4x-3|>13
so, 4x-3>13 or 4x-3<-13
x>4 or x<-10/4
so, solution set is, ]-inf,-5/2[union ]4,inf[

Answer 2

i got x < -2 or x >4 and the answer was x < -2.5 or x > 4.
i don't know how they got -2.5

Answer 3

start by adding 1 to both sides which gives

|4x - 3| > 13

now there are 2 inequalities to solve

4x - 3 > 13 and -(4x - 3) > 13

solve them for the compound inequality

Answer 4

OHHHH never mind hahah thank you!
