Answer:


-1<x<(-1)/(2).

Explanation:

We have the inequality


8\left|x+(3)/(4)\right| <2


\left|x+(3)/(4)\right| <(2)/(8)


\left|x+(3)/(4)\right| <(1)/(4)

The property we need to use is the property of the "less or equal":

|a+b|< c is the same as -c < a+b < c. Then


-(1)/(4)<x+(3)/(4) <(1)/(4)


-(1)/(4)-(3)/(4) <x<(1)/(4)-(3)/(4)


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


-1<x<(-1)/(2).

The graph is showed in the picture below.
